GNUPlot wordpress plugin v1.1

Friday, July 18th, 2008

Plots GNUPlot charts without GNUPlot on your server. This plugin communicates with our custom version of GNUPlot hosted at clker.com, and responds with a PNG chart or errors in case of errors.

Write your GNUPlot code between [ gplot] and [ /gplot] (without spaces). Maximum chart size is 1×1.

To install

  1. Copy the file ( gnuplot plugin ) in you wp-content/plugins directory, and rename to .php instead of .phptxt.
  2. Create wp-content/cache directory, and make sure it is write able to the webserver
  3. Activate the plugin from the plugins tab inside wordpress

Example:

[ gplot]

set size 1,0.7
set dummy u,v
unset key
set parametric
set view 60, 30, 1.1, 1.33
set isosamples 50, 20
set title "Interlocking Tori - PM3D surface with depth sorting"
set urange [ -3.14159 : 3.14159 ] noreverse nowriteback
set vrange [ -3.14159 : 3.14159 ] noreverse nowriteback
set pm3d depthorder
splot cos(u)+.5*cos(u)*cos(v),sin(u)+.5*sin(u)*cos(v),.5*sin(v) with pm3d,\
1+cos(u)+.5*cos(u)*cos(v),.5*sin(v),sin(u)+.5*sin(u)*cos(v) with pm3d

[/ gplot]

would produce this:

… Enjoy

GNUPlot wordpress plugin

Wednesday, July 16th, 2008

Newer version is here

While I was writing the repeated images identification post, I modified the mimetex wordpress plugin to be the GNUPlot wordpress plugin.

The plugin executes GNUPlot over any portion of the text enclosed between [ gplot] and [/ gplot] tags, without the spaces of course.

Example:

[ gplot]

set size 0.75, 0.3

set xrange[0:5]

plot sin(x) title “sin(x)”, sin(2*x) title “sin(2x)”

[/ gplot]

would generate:

Download: Download the GNUPlot plugin for wordpress

Installation:

- Make sure that your server has gnuplot installed

- Create the directory <wordpress>/wp-content/cache, and make sure it is writable by the web server

Enjoy :)
