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
<?plugin Ploticus device||=png [ploticus options...]
multiline ploticus script ...
?>
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.
