One of the things I wanted to add to the website was a graph of the output from our solar panels. I had a quick check round and came across two good candidates for this: easychart and Simple-Graph. Being me, I decided to try both – see the solar panel output page for the result.
Easychart can be used when you want to produce a professional looking chart and you have a fairly simple set of data to hand. Once you have installed the plugin, you simply construct a paragraph of text which defines all of the chart parameters and insert into any page you want.
Simple-Graph is designed to graph any quantity against time. The plugin adds a database table behind the scenes and gives you a data control page to load the data. It’s good for tracking your strength or weight for example.
Both of the approaches work well for the solar data – take your pick!
