Plot Over Time for WordPress
Uses the Google Chart Tools API for charting data entered in WordPress posts using MetaTags. Tracks up to 10 different data points, supports Area Chart, Line Chart, Pie Chart, Bar Chart, and Column Chart styles, any custom style options you’d like to include, and number of other options. Be sure to read the webpage for full notes and updates. Based on Tom Fotherby’s Fotherplot, however shares very little code with the original, and instead of requiring changes to a page or template, it uses shortcode to add graphs to a page or post.
