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.
set size 0.75, 0.3
plot sin(x) title “sin(x)”, sin(2*x) title “sin(2x)”
Download: Download the GNUPlot plugin for wordpress
- 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
