After working out how to plot time-based data using Google charts API, I created a WordPress plugin to plot values stored in a custom field against the published-on date of WordPress blog posts that use the field.
Usage Example
I use this plugin to keep a track of my weight. I have a private WordPress journal with a custom field called “Weight (kgs)” and each week when I make my journal entry I fill in my weight in this custom field. I have page called “My Weight” which is empty but uses the Fotherplot Template.
The plugin outputs a image and a list of the relevant data, example:
- January 17, 2009: 110.67kgs
- January 10, 2009: 113.4kgs
- January 3, 2009: 116.1kgs
- November 5, 2008: 110kgs
- October 18, 2008: 109.7kgs
- October 8, 2008: 112.9kgs
- August 30, 2008: 110.5kgs
- July 17, 2008: 103.4kgs
- April 8, 2008: 98.9kgs
- March 10, 2008: 99.3kgs
- February 11, 2008: 100.9kgs
- February 4, 2008: 102.3kgs
- January 28, 2008: 102.9kgs
- January 20, 2008: 103.4kgs
