Embeds GNUPlot charts inside your WordPress posts, without the need for GNUPlot on your webhost.
GNUPlot plugin allows you to draw charts inside your wordpress posts. The plugin will search the post for tags [gplot] and [/gplot]. Any thing in between will be used as a GNUPlot script, and resulting image will be placed in place of your tags.
The plugin communicates with a special version of GNUPlot hosted at clker.com, which means that you don't need to have GNUPlot on your system.
Not all the GNUPlot commands are allowed. All commands that will result in execution, shell, reading or writing from the server are disabled in the hosted version. The size of the chart is limited as well to avoid excessive CPU usage.
After your plot is generated, the plugin caches the result locally in wp-content/cache. You will need to make sure that this directory exists and is writeable by your webserver.
