Class diagram update * Add documentation on how to use background image * Review of theme management for pie Additions --------- * Add possibility to set the default start value for text labels * More examples of how to plot images and extended tutorial * Add date/time scale/axis type Verifications/Investigations: ----------------------------- * Possible bug when mixing grouped bar and lineplots * Have really all 0-value bugs been squashed? * Implement multi line text for legends * Check legends for grouped bar plots. Can we make that easier to use? * Check labels for 3d pies. * Check autoscaling with several scatterplots in a graph * Check if Setting manual scale in spider plot is a problem * Check potential problem with linlin and supplying both X and Y coordinates for a line plot * Check what happens with negative values for impuls plots when adding a line y=0. Possible scale bug? * Check the GroupBar and AccBar plot still work after the changes in BarPlot? Verification * Add testcase for negative/positive accumulated bar graphs * Fix error in documentation SetColor() is not a method of Class Legend * Fix problem whereby the first label on the x-axis is hidden when Y-axis has negative values and x-axis is positioned at 0 and setcenter() is used for the lineplot. Add a check to see if Setcenter is used and if that is the case the first label should not be hidden even if position is 0. * Merge the patch to make it possible to do CSIM without running the script off-line. * CSIM for Plot marks * CSIM for legends. Does this make sense? * Investigate the following report Also, I have discovered that in a graph with bars and lines, if the values are low (<50), the graph goes wrong (oversized bars, wrong scale, very big parse-time...). I have solved this. But if the values are lower (<10), the scale gets crazy. For example, for 0 to 3, the Y-Scale say : "blank-0-0-1-2-2-3" or similar. Also the graph takes VERY more time to generate. Also, I did notice that in sections 6.3.25 and 6.3.26 in the manual, the headings on the charts say "SpiderGraph" rather than "PieGraph." The General Description paragraph in both of those sections needs to be changed, too. * Possibility to just plot ticks/labels where the label is != "". Does this make sense? How should it work? * Linear scale investigation: Many datapoints and only show a grouped name for all values, for example sampling every hour but label each day (which is centered) * Filled line plots with negative values. What is the way to handle this? * Possibility to add text-labels directly in the new xxPlot() creation? Sometimes: ========== * Scientific plots. Investigate some use cases and see what changes needs to be done * Difference between minor/major tick marks for text-scale, i.e. ticks with and without text labels * Add pole-zero plots * Re factoring of the way Y and X axis are implemented. Redo the OOD so that we separate the notion of horizontal and vertical axis. This will get rid of the horrible non-oo tests axis=="x" jpgraph-1.5.2/src/jpgraph_error.php0100644000076400001440000000532407437547531016052 0ustar ljpusersPlot($datay,$datax); $this->numpoints /= 2; } //--------------- // PUBLIC METHODS function SetCenter($c=true) { $this->center=$c; } // Gets called before any axis are stroked function PreStrokeAdjust(&$graph) { if( $this->center ) { $a=0.5; $b=0.5; ++$this->numpoints; } else { $a=0; $b=0; } $graph->xaxis->scale->ticks->SetXLabelOffset($a); $graph->SetTextScaleOff($b); $graph->xaxis->scale->ticks->SupressMinorTickMarks(); } // Method description function Stroke(&$img,&$xscale,&$yscale) { $numpoints=count($this->coords[0])/2; $img->SetColor($this->color); $img->SetLineWeight($this->weight); for( $i=0; $i<$numpoints; ++$i) { $xt = $xscale->Translate($i); $yt1 = $yscale->Translate($this->coords[0][$i*2]); $yt2 = $yscale->Translate($this->coords[0][$i*2+1]); $img->Line($xt,$yt1,$xt,$yt2); $img->Line($xt-$this->errwidth,$yt1,$xt+$this->errwidth,$yt1); $img->Line($xt-$this->errwidth,$yt2,$xt+$this->errwidth,$yt2); } return true; } } // Class //=================================================== // CLASS ErrorLinePlot // Description: Combine a line and error plot //=================================================== class ErrorLinePlot extends ErrorPlot { var $line=null; //--------------- // CONSTRUCTOR function ErrorLinePlot(&$datay,$datax=false) { $this->ErrorPlot($datay); // Calculate line coordinates as the average of the error limits for($i=0; $iline=new LinePlot($ly); } //--------------- // PUBLIC METHODS function Legend(&$graph) { if( $this->legend != "" ) $graph->legend->Add($this->legend,$this->color); $this->line->Legend($graph); } function Stroke(&$img,&$xscale,&$yscale) { parent::Stroke($img,$xscale,$yscale); $this->line->Stroke($img,$xscale,$yscale); } } // Class /* EOF */ ?>jpgraph-1.5.2/src/jpgraph_pie.php0100644000076400001440000003072407437547531015500 0ustar ljpusers array(10,34,40,45,46,62,63,134,74,77,120,136,141,168,180,209,218,346,395,89,430), "pastel" => array(27,38,42,58,66,79,105,110,128,147,152,230,236,240,331,337,405,415), "water" => array(8,370,10,40,335,56,213,237,268,14,326,387,24,388), "sand" => array(27,168,34,170,19,50,65,72,131,209,46,393)); var $theme="earth"; var $setslicecolors=array(); var $labelformat="%01.0f"; // Default format for labels var $labeltype=0; // Default to percentage var $pie_border=true,$pie_interior_border=true; //--------------- // CONSTRUCTOR function PiePlot(&$data) { $this->data = $data; $this->title = new Text(""); $this->title->SetFont(FF_FONT1,FS_BOLD); } //--------------- // PUBLIC METHODS function SetCenter($x,$y=0.5) { $this->posx = $x; $this->posy = $y; } function SetCSIMTargets(&$targets,$alts=null) { $this->csimtargets=$targets; $this->csimalts=$alts; } function GetCSIMareas() { return $this->csimareas; } function AddSliceToCSIM($i,$xc,$yc,$radius,$sa,$ea) { //Slice number, ellipse centre (x,y), height, width, start angle, end angle //add coordinates of the centre to the map $coords = "$xc, $yc"; //add coordinates of the first point on the arc to the map $xp = floor(($radius*cos($sa))+$xc); $yp = floor($yc-$radius*sin($sa)); $coords.= ", $xp, $yp"; //add coordinates every 0.2 radians $a=$sa+0.2; while ($a<$ea) { $xp = floor($radius*cos($a)+$xc); $yp = floor($yc-$radius*sin($a)); $coords.= ", $xp, $yp"; $a += 0.2; } //Add the last point on the arc $xp = floor($radius*cos($ea)+$xc); $yp = floor($yc-$radius*sin($ea)); $coords.= ", $xp, $yp"; if( !empty($this->csimtargets[$i]) ) $this->csimareas .= "csimtargets[$i]."\""; if( !empty($this->csimalts[$i]) ) { $tmp=sprintf($this->csimalts[$i],$this->data[$i]); $this->csimareas .= " alt=\"$tmp\""; } $this->csimareas .= ">\r\n"; } function SetTheme($t) { if( in_array($t,array_keys($this->themearr)) ) $this->theme = $t; else JpGraphError::Raise("JpGraph Error: Unknown theme: $t"); } function ExplodeSlice($e) { $this->explode_radius[$e]=20; } function ExplodeAll($radius=-1) { $this->explode_all=true; if( $radius==-1 ) $this->explode_r = 20; else $this->explode_r = $radius; } function Explode($radarr) { $this->explode_radius = $radarr; } function SetSliceColors($c) { $this->setslicecolors = $c; } function SetStartAngle($a) { assert($a>=0 && $a<2*M_PI); $this->startangle = $a; } function SetFont($family,$style=FS_NORMAL,$size=10) { $this->font_family=$family; $this->font_style=$style; $this->font_size=$size; } // Size in percentage function SetSize($size) { if( ($size>0 && $size<=0.5) || ($size>10 && $size<1000) ) $this->radius = $size; else JpGraphError::Raise("JpGraph Error: Size (radius) for pie must either be specified as a fraction [0, 0.5] of the size of the image or as an absolute size in pixels in the range [10, 1000]"); } function SetFontColor($color) { $this->font_color = $color; } // Set label arrays function SetLegends($l) { $this->legends = $l; } // Should the values be displayed?

Changes/Additions: ------------------ * [me] Added possibility to use "auto" file name when stroking directly to a file. * [me] Added tag 'title' to the image maps to make for better compatibility with Mozilla. * [me] Moved class LineProprty to jpgraph.php from jpgraph_gantt.php since it can be used in other modules as well. * [me]Added Text::GetTextHeight() which differs from Text::GetFontHeight() in that it takes the total text height (possible multiple lines) into account. * [me] Added Image::FilledArc() * [me] Added RotImage::SetTranslation() Added RotImage::Circle() Added RotImage::FilledCircle() Added RotImage::Arc() Added RotImage::FilledArc() [11-Feb-2002] JpGraph 1.5.1 =========================== * [me] No longer treat a not set $y[0] value as an explicit error. Instead silently set $y[0] to 0. * [me] Changed "include" to "require" in jpgraph.php when including jpgraph_dir.php. This seems to fix the strange problem whereby the constants defined in jpgraph_dir.php didn't have a correct value in jpgraph.php. * [me] Fixed problem with correctly drawing of bars when all bars are negative. (Previously the baseline wasn't correctly handled since min/max values needs to be mirrored for negative bars) Note: Funny this problem has gone unnoticed so long. * [me] Fixed problem with doing gradient fill for negative bars. * [me] Fixed problem with autoscaling when there is a very small difference (< 0.00001) between min and max and when both min and max are negative. This might happen if you have a single negative value. * [me] Added labels for line graph. Each point my now also optionally display it's value on a line graph. Value are controlled trough class DisplayValue and it's instance in LinePlot. LinePlot->value->Show(), LinePlot->value->SetColor(), LinePlot->value->SetFont(), LinePlot->value->SetMargin(), LinePlot->value->SetFormat(), [27-Jan-2002] JpGraph 1.5 ========================= * [me] Fixed misnamed xmin variable in Min() for acc bars * [me] Added possibility to specify paragraph alignment for multi line text, i.e the text can be left,right or center aligned within it's bounded box. The lignment is set by the new method Text::ParagraphAlign() * [me] Changed position specification for text so that if the position is specified in range [0,1] it is interpreted as fraction of image height width and otherwise as absolute pixels. * [me] Added possibility to specify pie size (radius) both as a fraction and absolute size in pixels. * [me] Added possibility to tweak color specification by adding a saturation percentage, i.e you can specify color as "red:0.65" which means 65% of the red value (in other words 35% darker). * [me] Tweaked the estimation of number of segments to approximate an arc in Image::CakeSlice. [17-Jan-2002] JpGraph 1.5beta2a =============================== * [me] Fixed typo in Max() calculation for accumulated bar graphs which caused it to return wrong value. * [me] For Min() calculation for acc bars graphs take the user specified ymin into account. * [Peter Svistunov, me] Added Cyrillic unicode support through the global define LANGUAGE_CYRILLIC. This is also the start of a generic support for Unicode languages through the LanguageConv class. [15-Jan-2002] JpGraph 1.5beta2 ============================== * [me] Rewrite of the pie-chart drawing algorithm. This version is slightly slower but avoids using GD floodfill function. This fixes problems with small slices not being filled completely. As an added bonus it is now possible to explode (and specify the explode radius) for all slices. It is also possible to draw the pie without having internal borders between the slices as well as turning on/off the border surronding the pie. * [me] Added graphic primitive CakeSlice() to the Image class. Used to simplify pie-drawing. * [me] Added more generic error handling. It is now possible to install your own error object with JpGraphError::Install() The default error handler will just abort execution. * [me] Security whole in utility script for displaying source and image in frames fixed. * [Cedric Scheyder] Actively ignore hours in calculating Max/Min values for dates in Gantt charts to avoid problems in autoscaling when users specify start and end dates down to hours. * [Rick Widmer] Fixed problem in calculating min/max value when first Y-value was non-numeric. * [me] Fixed calculation of width and height of text with multiple lines. Multiple text lines (text blocks) should now be almost fully supported. [16-Dec-2001] JpGraph 1.5-BETA ============================== * Take "\n" into (some) account when calculating string height and width Text output now supports multiple lines better. * [me] Removed reference to global PHP_SELF, use HTTP_SERVER_VARS array instead. This makes JpGraph working with 'register_globals' turned off. * [me] Added some rudimentary check that GD is enabled before trying to run JpGraph. * [me] Fixed silly cut-and-paste bug in AccBarPlot::Max() which could cause to small max values to be returned * [me] Added property 'title' to PlotMark. The title is printed in the center of the plotmark. * [DanNY (dulcis28@hotmail.com)] Added JpGraph Logo. (Thanks!) * [me] Added jplintphp.php, jpgendoc.php, jplintdriver.php which are parsing, documentation and pretty printing tools I use to help me to documentation and find unused code. Tthat does some simple static analysis on PHP for silly mistakes that I do (Like using instance variables without qualifying them with "$this->" ) The tool also warns about unused instance variables. Since it also parses the classes and methods I use it to generate the documentation skeleton for the reference section. * [me] Added Gantt chart funcionality, jpgraph_gantt.php . See Gantt tutorial for help on usage. * [me] Added new Gantt tutorial * [me] Added BKIMG_CENTER, possibility to center the background image. * [me] Timeout function now also aplies when you generate an image off-line, i.e if the imagefile exist and is within the time window now file will be written. * [Rasmus Lerdorf] Added patch to make background images work with GD 2.x N.B GD 2.01 has bugs in handling TTF font with truecolor images which are fixed in 2.02 but that has (of this writing) still not been officially released. GD 2.x support in JpGraph is still to be considered experimental. * [me] Fixed some potential rounding errors in 2D Pie plot which in some circumstances might have caused a flood fill to escape. Also added check to better handle very small slices so we don't try to do a fill on the border edge. * [me] Slightly changed the internal design for band patterns. They are now created by a factory class instead. This makes it much easier to re-use and have maximum code reuse. * [me] Factored out some functionlity from Graph::Stroke() to make it possible to re-use some code in GanttGraph::Stroke() * [me] One more instance when PHP surprised me by thinking 0 == "-" aarrghhh Now I think (knock on wood) all problems with data points=0 should be solved * [me] Added '&' to the assignment in Graph::Add() This now lets you specify changes for lines, plots even after they been added to a Graph. But I'm not sure if this is really such a good ide because you will have problem if you write code like for( .... ) { $myplot = new LinePlot(.....); $graph->Add($myplot); } Since this will not work the way you think (why?) Because the same reference to the variable $myplot will be used for all additions and hence the graph will only have multiple instances of the last added LinePlot(). Have to think of this and what is the best way. (I will probably never get used to PHP references....) [11-Nov-2001] JpGraph 1.4 ========================== Bug Fixes: ------------------------------------------------------------------------------------- * [me] Enabled E_NOTICE warnings in my PHP installation and found a couple of glitches (harmeless out-of-bound in two loops) which is now corrected. * [me] Fixed problem in line plots where y-value==0 wasn't drawn. (Once again bitten by the fact that in PHP the following is true: ""==0) * [me] Fixed color specification for bars when initialized as an array of colors * [me] Fixed color of bars using shadow which was advertedly set to shadow color * [me] Fixing incorrect color specification for legends using bars with color arrays * [me] Add check for sum=0 in pie plots to avoid divide by 0 problem * [me] Changed the stroke orderd for FilledRectangle() so that the shadow doesn't overwrite a line with weight > 1 * [me] Fixed incorrect calculation of font height for titles which cause the subtitle to be to close to the title. Additions: ------------------------------------------------------------------------------------- * [me] Added depth parameter (DEPTH_FRONT, DEPTH_BACK) for gridlines Graph::SetGridDepth() * [me] Added possibility to add static horizontal and vertical band with a pattern in the plot area. Graph::AddBand() Supports solid, diagonal, stright line, 3D-plane crosses (both diagonal/vertical) patterns. Graph::AddBand() * [me] Added possibility to have static lines in the plot. This is now implemented with new class PlotLine and two new functions Graph::AddLine(), * [me] Added symbolic constants to specify background image types BGIMG_COPY, BGIMG_FILLPLOT, BGIMG_FILLFRAME * [me] Added extended label formatting through either Axis::SetLabelFormatString() C-style formatting string or Axis::SetLabelFormatCallback() A callback function that are given the value to be displayed and should manipulate the value as it likes The use of the old style digit precision variable will be deprecated from next version. * [me] Added error check if supplied Y-data has unspecified value at index 0 to avoid out of bounds error when corrupted data is sent in to JpGraph. * [me] Added possibility to specify image depth for gridlines. You can now specify Graph::SetGridDepth() as DEPTH_FRONT or DEPTH_BACK. Depending on if you want the gridlines at the back of in front of your plots. * [me] Added possibility to specify Cache file name as "auto". In this case the image file name will have the same name as the scriupt that generates the image with the extension of the automtically generated graphic format. NOTE: You will get the wrong extension using this feature at the same time as specifying a different graphic format thne the automatically choosen one. * [me] Added some more advanced examples for impuls drawings impulsex3.php and impulsex4.php * [me] The values on top of bars can now be at an angle and the horisontal position now account for if a shadow is present. * [me] Added filename to Graph::Stroke() which makes it easy to output an image directly to a file _without_ streaming it back to the browser. Usefull for batch processing * [me] Added new tutorial for bar graphs * [me] New scale type "int". This gives a normal linear scale but restricts ticks (and labels) to integer values. Can be used for both X and Y scales. * [me] Added subtitle to graph * [me] Added possibility to specify an array of X-coordinates with bar plots to position individual bars on the X-scale. Makes it much easier to combine bar plots with other types of plots, (line, scatter etc) * [me] Extended utility adjimage.php to allow it to manipulate color saturation. * [me] Added Image::AdjSat() to allow manipulation of the color saturation in the image. This also makes it very easy to change the image to greyscale (just set saturation=-1). Extended Graph::AdjImage() and Graph::AdjBackgroundImage() to include new parameter for saturation value. * [me] Added BarPlot::SetAlign() which makes it possible to align bars relative the tickmark for linear and int scale * [me] Added possibility to absolutely set the width of bars. This will override the automatically decided with based on the scale and tick distance Changes: ------------------------------------------------------------------------------------- * [me] Legend color for scatter plots now becomes the fill color of the mark * [me] Impulsplots now anchors at Y-value = 0 if the y-axis contains both negative and positive values. Otherwise it will go to the lowest value on the Y-axis. * [me] Bar shadows is now connected to bars to make for a stronger 3D effect. * [me] Removed all deprecated references and usage of FONT0, FONT1, FONT2. Note You can no longer use these. Instead use FF_FONT0, FF_FONT1, FF_FONT2 etc * [me] Text scale now starts default labelling at 0 * [me] All plots internally adjusted to start at default X-coordinate 0 to harmonize better with X-scale. * [me] Graph->Stroke() now just returns instead of exit() * [me] Removed flag argument for BarPlot::SetShadow() * [me] Bar plots are know by default filled with lightblue unless otherwise specified. * [me] Changed the way bars are positioned for linear and integer scale for maximum flexibility when mixing barplot with other plots. * [me] The ALT strings for all image maps now uses printf() syntax to display the actual value. If you have used this feature you must update your ALT strings, for example "val=%v" must become "val=%d" or whatever format you choose. * [me] Changed the formatting of bar graphs by changing the framework so that labels on the x-axis using a text scale is now independent on the tick marks. This makes it possible to have the labels centered under each bar but have the tickmarks between the bars as most other commercial graph packages format these typw of graphs. Introduced Axis::SetTextLabelsInterval() Effects jpgraph.php, jpgraph_log.php and jpgraph_bar.php * [me] Renamed Axis::SetTextTicks() to Axis::SetTextTicksInterval() to make the name more descriptive. The old name is deprecated from this version on but will still work until 2.0 to keep compatibility. * [me] Cleaned up implementation of pie3d so it now inherits from pie to avoid a lot of duplicated code and easier maintainance. (A good example of the real life OO programming where you might not see the similarities between two classes until you fully implement them.) File size of jpgraph_pie3d.php has shrunk by roughly 40% [23-Sep-2001] JpGraph 1.3.1 =========================== Additions: * [Michael Anthon] Added client side image maps to 3D pie plots * [me] Added possibility to better control the labeling of pie graphs with an optional label formatting string PiePlot::SetLabelFormat(), PiePlot::SetLabelType() This also makes it possible to have labels with the absolute value and not only the percentage. (same with pie3d) * [me] Added formatting capabilities for legends on pie and pie3d graphs. Can have the value automtically included (Se Examples/pieex6.php) * [me] Added some more examples, negbarvalueex1.php, scatterlinkex2.php, pie3d_csimex1.php pieex6.php Known bugs and omissions: - Client side image maps does not currently handle exploded pie graphs (just normal pie graphs. Bug fixes: * [me] Fixed problem with positioning the displayed values for negative bars * [me] Fixed shadow for negative bars * [me] Fixed problem in Plot::Min(), PlotMax::Max() whereby zeros where not counted towards minimum since in PHP 0=="". This could sometimes cause strange autoscaling. * [Vitaly E. Ashmarin] Wrong arguments to imagejpeg() for combination of specified image quality and filename = "" * [John Milne] BarPlot::SetFillColor() fixed glitch in loop variable [13-Sep-2001] JpGraph 1.3 ========================= Note: I have to the best of my memory tried to give credit where credit is due. Howevever, since ver 1.2.2 I have received over 2000 mail about JpGraph with Questions/Suggestions/Improvments (and a few bug fixes) etc and I might have missed some in the process of going through these mails. The fault is completely my own and if you recognize some idea I have implemented something which you think you should have credit for please drop me a note and I will adjust the add you to the change notes. Known bugs and omissions: - The automatic value on bar graphs does not work well with negative bar graphs. (Quite easy to fix though..) - Client side image maps does not currently handle exploded pie graphs (just normal pie graphs. IMPORTANT NOTICE: * SC (SOURCE COMPATIBILITY) BREAK !: If you want to rotate the image the parameter is no longer supplied directly in the call to Graph() but rather as a method call Graph::SetAngle(). I decided to make this SC break since I judged it more natural to supply the timeout value just efter the specified cache-file name in the Graph() call. Hopefully this will not hit to many people since my hunch is that few people uses the rotate function and it's very easy to fix those script that does so. Bug Fixes: * [michael@anthon.net] Corrected behviour of accumulated bar graph so it now diffrentiate between the accumulated positive and negative values. * [marko@fly.srk.fer.hr] Fixed Max() calculations for accumulated bar graphs where my original code was a little bit sloppy. (I simply took the max for each plot and added those and this might be more then the real maximum.) * [m.purgar@extracom.de] Spotting an incorrect "jpg" in the image where it should have been "jpeg" * [adam.blomberg@euroseek.net,patrik.johansson@euroseek.net] 3D-Pie filling problem for small slices due to the discrapency between GD arc() and the JpGraphs purely mathematical definition of an ellipse. * [delorme.maxime@free.fr] 2D-Pie Floodfill might "escape" for very small values of slices. * [et.al] Improved handling of 0:s vs "" values. This was necessary since PHP treats 0 as "" the same in a number of situations and JpGraph needs to diffrentiate these two cases. This caused 0 data values to be treated as null values and not be inluded in (for example) autoscaling consideration. Additions: * [me] Added new global constant USE_CACHE which makes it possible to disable writing to the cache even if a filename is supplied in th Graph::Graph() method. * [me] Added LinePlot::SetStyle() to make it possible to make dashed, dotted etc lineplots. (See example1.2). Also adjusted legend to display the same style in the legend. * [michael@anthon.net, me] Added client side image maps for all types of bars and 2D pies with possibility to have the actual value shown in an ALT-tag. * [me] Added drop shadow (or rather "right-up" shadow) to bar graphs BarPlot::SetShadow() * [me] Added possibility to have the actual value of bar graphs displayed at top of graphs via BarPlot::ShowValue(), BarPlot::SetValueFont(), SetValueMargin(), SetValueColor() The format of the value is specified according to standard C printf() string formatting i.e. "val=%d" will for example print a string "val=13" * [me] Added possibility to adjust brightness and contrast for background image via the Graph::AdjBackgroundImage() method. * [me] Added possibility to adjust brightness and contrast in the finished image via the Image::AdjBrightContrast() method. * [me] Added possibility to just generate an image to a file and not stream it directly back to the browser. Added parameter $aInline to Graph::Graph() * [me] Added timout for cache, i.e if the image in the cache is older then the specified number of minutes (=0 never re-generate, -1 always regenerate) then re-generate the image. Just specify a timeout in minutes with a call: $mygraph->cache->SetTimeOut(10) * [me] Added possibility to use logarithmic scale for SpiderPlots. This also resulted in a little bit of internal cleanup in jpgraph_spider.php. * [me] Added SetWeight() method to class Ticks() for control of line thickness for ticks * [me] Added SetMarkColor method to class TIcks() which lets you specify different colors for major and minor tick marks. * [me] Added method RelTranslate() to LinearScale() and LogScale() classes which is used in Spider class. This makes a world to screen relative translation. * [me] Added possibility to link data points in a scatter plot with lines by the addition of method ScatterPlot::SetLinkPoints() * [me,john.milne@one2one.co.uk] Added possibility to have individual colors of bars in bar graphs by having BarPlot::SetColor() accept an array as argument. * [sergio@alsernet.es] Make it possibly to have x-tick labels to consist of two lines by inserting a "\n" separator in the text. * [CK1@wwwtech.de] Adding JPEG quality setting. This is done by adding a method SetQuality() to the img class. After creating a graph this can then be used as $mygraph->img->SetQuality($some_qvalue). Currently this only affects JPEG images. * [delorme.maxime@free.fr] Possibility to use different grace value for top and bottom of graph and not just a single value as in 1.2.2 Changes: * [me] Changed group/permission handling for created files to better adjust itself to the way the local Apache user is setup * [me] The default for spider graphs is now NOT to be filled * [me] Allow all datapoints to be 0 which will set the scale to [0,1] * [me] Removed the need for a DIR_BASE variable [29-Apr-2001] JpGraph 1.2.2 =========================== Bug fixes: * Removed reference to non-existent property 'bypass' in class RotImg * Changed to allow the last X-gridline to be drawn (comparison with limit was '<' where it should have been '<=' ) Additions: * Added possibility to use background image * Added possibility to use approximate color through the "USE_APPROX_COLORS" constant * Handling of diffrent form of "null values" for line graphs. An y-value can now be "" or "-". In the first case (a true null value) this mark will cause a disruption in the line graph to indicate that the value is undefined. In the other case specifying the value as "-" will cause the value to be ignored bu the line will still be drawn between the previous data point and the following. Neither of these cases will have any mark drawn. * Added a fatal warning when no more colors can be allocated for the chosen graphic format. Changes: * "Downgraded" anti-aliasing algorithm to use fewer color levels in the transition to avoid using up to much of the color palette * Cleaned up some of the code to not rely on PHP default initialization of variables. This will help those who have got warnings when they have had all error reporting enabled in php.ini (E_ALL) * Legends now show the plot mark (if defined) instead of just a square of the right color. Acknowledgements: * Thanks to kevin@pricetrak.com for suggesting the treatment of pure NULL values. * Thanks to luca_n@hotmail.com for getting my attention to the warnings caused by relying on PHP default initialization of variables. (My installation had E_NOTICE disabled, hence I never got those warning myself.) [29-Mar-2001] JpGraph 1.2.1 =========================== Bug fixes: * When min and max values for autoscaling was equal this resulted in trying to calculate log10(0) = INF resulting in an infinite loop in LinearTicks::Stroke() * When autoscaling was used with only one data point it tried to calculate log10(0) = INF resulting in an infinite loop * fopen("xxx","r") should be fopen("xxx","rb") causes problems on windows system with IIS5 * JPG streaming function was incorrectly called "imagejpg" should be "imagejpeg" (see the difference?) * Non existent color name in jpgraph_pie.php * Removed all deprecated forced references in function calls * The width of the surrunding box was not calculated correctly for internal bold font Additions: * Color themes for pie graphs * Beta release of 3D pie graphs * Added DIR_BASE as constant to make it possible to use one system wide copy of JpGraph. NOTE: This must be set to the directory where JpGraph is installed. Acknowledgements: * (ck1@wwwtech.de) (and a russian guy which I unfortunately lost the name of) for reporting the imagejpg spelling mistake * (ales.gregor@zps.skoda-auto.cz) for finding the binary file problem with IIS * Several people have reported the problem with autoscaling when all Y-values were equal. Thanks to you all for acting as my privet QA team! [18-Mar-2001] JpGraph 1.2 ========================= Additions: ---------- * Added "BRAND_TIMING" which give possibility to brand each image generated with the time (in ms) it took to generate the image. * Added Gradient Fill for bar graphs, The gradient fill allows 6 different styles. * Added Anti-aliasing for lines. Note drawing anti-aliased lines is 7-10 times slower then "normal" lines! * Added full TTF support. this means an internal SC break (Source Code Break). Normal JpGraph script should not be affected if you have used only publized "public" frunctions. The SC break is to allow uniform treatment of both internal fonts and TTF. This has been achieved by changing the parameter list for SetFont(). However, backward compatibility with the old naming conventions for internal fonts are kepot, e.g. SetFont(FONT1_BOLD) still works but is deprecated and will not be valid from 2.0 * Added possibility to control font for title of Spider Axis through the added property 'title' to the axis in the spider graph. * Added 'SetColor()' in pie graphs as a shortcut to SetMarginColor() to set the background color * Added possibility to draw X-axis labels at arbitrary angle. Internal fonts only supports horizontal and verical. * Added possibility to draw boxed text at an angle * Added possibility to have different colors for axis and the labels on the axis by the addition of extra parameter to SetColor() * Added 350 more named colors. * Added canvas "fake" graph to make it easy to draw arbitrary graphics * Added SetCenter() method for line graphs. * Added SetGrace() for autoscaling purposes. Changes: -------- * If you use a text-scale for X-axis the default labels now start at 1 instead of 0 since this is actually a counting scale and it makes more sense to start at 1. * Improved handling of bar-graphs with negative values. * Updated existing examples to use new format for SetFont() * Made it a critical error to specify a non existant font * Changed so that orientation for Text() is now given as an angle, i.e. SetOrientation(45). Old style of using SetOrientation("v") (for vertical) is deprecated. But will work until V2 Bug fixes: ---------- * Improved handling of computational effects on small values in scaling where a rounding error might cause the last label not to be drawn. * The position for the title of X-axis could in some cases be slightly different in first and second pass due to incorrectly determination of the X-axis labels font height. * Specifying an minimum Y-value for Y-axis on bar graphs could on rare occasions (combination of scale values and specified density of autoscaling ticks) cause a gap between the bottom of each bar and the X-axis. [18-Feb-2001] JpGraph 1.1 ========================= Additions/Changes: ------------------ * Added Spider graphs * Added Pie graph * Added Scatter (and impuls) graphs * Added possibility to rotate plots an arbitrary angle * Added step style rendering to lineplot * Added Breseham circle drawing which gives better visual apperance then the built in Arc() in GD (on the expense of CPU and performance) * Improved Polygon and Rectangle drawing so that it will use line weight settings * Improved the visual appearance of lines with weight>1 by correctly calculating (angle wise) the endpoints and using a filled polygon to draw the line. Unfortunately it would require some real improvements in the GD library to really improve the visual appeance of lines with weight>1. This is as good as it gets without writing a low level pixe-by-pixel correct plotting. With my method you get it to look visually aestethic right in 90% of the cases with just 10% work. * Added MARK_FILLEDCIRCLE as new mark type. Note that due too the poor performance of the basic Arc() image primitive in PHP4 the circles isn't perfect circles, they tend to be a a little bit flat at multiples on PI/2. * Added the possibility to have a separate fill- and line- color for marks * Moved Class PlotMark from jpgraph_line.php to base in jpgraph.php since this class is also used with scatter plots. * Made it a critical error to try to use Text X-scale with specified X-data points. Previously no warning was given for this non-defined state. (Using text scale with specified points really doesn't make sense.) * Made it a critical error to use unknown color rather than silently replacing it with black. * Updated documentation to reflect added capability Bug fixes: ---------- * Fixed minor bug in Line() in which it didn't update the last point for use with subsequent LineTo() calls (forgotten $this->) * Eliminated assumptions in DashedLine() that x1<=x2 and y1<=y2 eliminates the potential pixel overshoot. * Fixed a serious bug in Line plot when used with a specified X-scale (not the normal default) since the X-coordinate wasn't read from the correct vector! * Fixed a serious bug whe using as specified X-scale since the maximum value for a plot wasn't correctly passed to the autoscaling. Note: The reason that these two bugs haven't been discovered previously is the fact that my test specs didn't include test cases to do with specified X-axis (I almost never ever use that). This has now been corrected and added to the test suit. * Fixed so the possible box around the plot area correctly honours the weight specified for it. [05-Feb-2001] JpGraph 1.0 ========================= * Initial release.

The library is released under GPL 2.0. See COPYING for details about this license. The whole libray is Copyright (C) 2001,2002 Johan Persson and released under GPL 2.0 Included files -------------- README This file COPYING GPL 2.0 Licensee /image_gallery Point your browser to index.html in this directoryt to have a quick view on images from the examples in ./src/Examples /src Changelog Changelog for JpGraph Todo ToDo list for future releases jpgraph.php Base library jpgraph_dir.php Directory paths for base library jpgraph_log.php Extension: logarithmic scales jpgraph_line.php Extension: line plots jpgraph_bar.php Extension: bar plots jpgraph_error.php Extension: error plots jpgraph_scatter.php Extension: scatter/impuls plots jpgraph_spider.php Extension: spider (Web) plots jpgraph_pie.php Extension: pie plots jpgraph_canvas.php Extension: drawing canvas jpgraph_pie3d.php Extension: 3D pie plots jpgraph_gantt.php Extension: Gantt chart /src/utils/ gencolorchart.php Unsupported utility to generate a sample color chart of all named colors adjimg.php Unsupported utility to change contrast/brightness for an image. jplintphp.php Unsupported base library to parse PHP files jplintdriver.php Simply driver for running lint over a file and warns for unused instance variables and possible forgotten $this-> jpgendoc.php Extended driver which uses jplintphp base library to generate a HTML template for a class reference. /src/Examples A directory with over 80 example graphs. Run jpgraph_testsuit.php to get a list of all files and you can easily click on a file to see the code and the resulting image. Requirements: ------------- * PHP 4.02 or higher * GD 1.8.x, Experimental support for GD 2.x CAVEAT 1: JpGraph is developed under Unix and is known to work well. Please note that you may or may not encounter some known issues when trying to run on PHP/Apache/Windows or a combination of PHP/IIS. See below. CAVEAT 2: To get background images working with GD 2.0.1 you MUST enable Truecolor images by setting the constant USE_TRUECOLOR to true. If you don't fo this the background images will just be a black rectangle. The bad thing with this is that the antialias for Truetypes is broken using truecolor images in GD 2.0.1. This means you can't have background and TTF fonts in the same image. Installation ------------ 0. Make sure your PHP is AT LEAST 4.02 (preferrable 4.1.1) and that you have compiled support for GD library. You must make aboslutely sure that you have GD working. Please run phpinfo() to check if GD library is supported in your installation. Please not that JpGraph only fully supports GD 1.x. There are known issues with GD 2.0.1. 1. Unzip and copy the files to a directory of your choice. 2. Set up the directory paths in jpgraph_dir.php where the cache directory should be and where your TTF directory is. Note that Apache/PHP must have write permission in your cache directory. Caveat: On windows there seems to be some problem with including this file and you might have to move all the defines directly into jpgraph.php. If you get an error saying "Font not found" and you have specified the correct font path try the above mentioned workaround. (See also paragraph 5 below) 4. Check that all rest of the DEFINE in the top of JpGraph.php is setup to your preference. The default should be fine for most users. (See also Note 5. below) 3. Make sure PHP have write privileges to your cache directory. 4. Some windows installations seems to have a problem with a PHP script ending in a newline (This newline seems to be sent to the browser and will cause a Header already sent error). If you have this problem try remove all trailing newlines in the jpgraph* files 5. It has been reported that PHP 4.06 under IIS has problem correctly interpreting file paths. This can be solved by hardcoding the CACHE_DIRECTORY and FONT_DIRECTORY const ants directly in the code instead of using the defined constants. 6. Read the FAQ on http://www.aditus.nu/jpgraph/jpg_faq.php. Troubleshooting --------------- 1. Any PHP errors about function "imagecreate" does not exist indicates that your PHP installation does not include the GD library. This must be present. 2. Any error about "parent::" undefined means that you are not using PHP 4.02 or above. You _NEED_ PHP 4.02 or higher. This problem has also been reported to sometimes occur under Windows. This problem has also been reported by people running Zend-cache and is a bug in Zend. A workaround is to move all files into one single file. 3. If you don't get any background images (but rather a black background) you are most likely using GD 2.x which is not yet supported. JpGraph has only been verified with GD 1.x 4. If you are running PHP 4.06 and get an error saying "GD was not built with truetype support" you should know that this is a known problem with GD+PHP 4.06. There are some workarounds (search the net!) but it is really recommended that you instead upgrade to at least PHP 4.1.1 and configure PHP with --with-gd-native-ttf (Please also note that the built in TTF uses point size for fonts whereas Truetype 2 uses pixels.) Please DON't ask me how to resolve the GD Font problem. All mail regarding this will go straight to /dev/null. Upgrade to 4.1.1! 5. If you are running IIS and Win2k and get the error "Can't find font' when trying to use TTF fonts then try to change you paths to UNIX style, i.e. "/usr/local/fonts/ttf/". Remember that the path is absolute and not relative to the htdocs catalogue. 6. If you are using the cache please make sure that you have set the permissions correctly for the cache directory so that Apache/PHP can write to that directory.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.
