About GNUPlot
From the official readme · v1.0Description
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.
