The Ploticus WikiPlugin passes all its arguments to the ploticus
binary and displays the result as PNG, GIF, EPS, SVG, SVGZ or SWF.
Ploticus is a free, GPL, non-interactive software package
for producing plots, charts, and graphics from data.
See 
http://ploticus.sourceforge.net/doc/welcome.html
Usage
<verbatim>
<?plugin Ploticus device||=png ploticus options...
multiline ploticus script ...
?>
</verbatim>
Plugin Arguments
| device: | gif, png, jpeg or svg. Soon also PS or SWG. Default: png |
|---|---|
| data: | optionally add data by <!plugin-list !> pagelist plugins. |
| alt: | alt text for the image |
| -prefab: | use the given prefab script (may need $_ENV['PLOTICUS_PREFABS']) |
| -csmap: | If a clickable map should be produced (not yet tested) |
| help: | Show a help screen (not yet) |
Known Problems
- For windows you need either a gd library with GIF support or a ploticus with PNG support. This comes only with the cygwin build so far.
- We support only images supported by GD (PNG most likely) and now also SVG. MAP support not yet tested. No EPS, PS or SWG support yet.
Examples
<?plugin Ploticus device||=png
- proc page
if @DEVICE in gif,png
scale: 0.7
- endif
// specify data using {proc getdata}
- proc getdata
data: Brazil 22
Columbia 17 "Costa Rica" 22 Guatemala 3 Honduras 12 Mexico 14 Nicaragua 28 Belize 9 United\nStates 21 Canada 8
// render the pie graph using {proc pie}
- proc pie

The pie chart above was produced by this code from the ploticus testsuite:
<verbatim> <?plugin Ploticus device||=png alt="Sample Pie Chart"
- proc page
if @DEVICE in gif,png
scale: 0.7
- endif
// specify data using {proc getdata}
- proc getdata
data: Brazil 22
Columbia 17 "Costa Rica" 22 Guatemala 3 Honduras 12 Mexico 14 Nicaragua 28 Belize 9 United\nStates 21 Canada 8
// render the pie graph using {proc pie}
- proc pie
firstslice: 90 explode: .2 0 0 0 0 .2 0 datafield: 2 labelfield: 1 labelmode: line+label center: 4 4 radius: 2 colors: yellow pink pink pink pink yellow pink labelfarout: 1.05 ?> </verbatim>
