View Source: PloticusPlugin

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. !!
