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

  1. 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.
  2. 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 failed. sh: /usr/local/bin/pl: No such file or directory

The pie chart above was produced by this code from the ploticus testsuite:

<?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
