The software allows you to generate GNUPlot charts on your server without the need for installing GNUPlot. It simplifies the chart plotting process by eliminating the hassle of software installations, enabling users to focus on generating high-quality charts.
To use this plugin, users simply need to write their GNUPlot code between the designated [ gplot] and [ /gplot] tags (without spaces). The maximum chart size is limited to 1×1.
Installation is simple and involves three steps. Firstly, the user needs to copy the 'gnuplot plugin' file to their wp-content/plugins directory, and rename it to .php instead of .phptxt. Secondly, they need to create a wp-content/cache directory and ensure that it has write permissions enabled for the webserver. Finally, the plugin can be activated from the plugins tab inside wordpress.
As an example, the following code can be used to plot interlocking tori in the PM3D surface with depth sorting:
[ 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].
Overall, the GNUPlot Wordpress Plugin is a convenient tool for those who need to plot charts but do not have GNUPlot installed on their server. The installation is straightforward and the plugin is easy to use with clear instructions provided.
