I wanted a way to create a WordPress plugin that enabled me to build coffee cupping charts for my Coffee Troupe blog. I started with a PHP library called pChart pchart.sourceforge.net and modified it to make it into a WordPress plugin.
The syntax to build this sample is:
[TASTE:Yirgacheffe Ethiopia:8.5,9,8.5,8.75,9.1,9.5,8.5,8,7.5] – uses the cached image it builds first time
[TASTE:Yirgacheffe Ethiopia:8.5,9,8.5,8.75,9.1,9.5,8.5,8,7.5:rebuild] will force the image to be rebuilt every time.
The spokes of the graph are defined in the control panel so you can set your own parameters to score on.
The graph above is just a sample. I put in random scores to demonstrate the result.
