This plugin allows you to easily insert charts into your blog, making use shortcodes. While multipurpose, the chart system is intended to make it easy for posting detailed review measurements of some sort, such as video card comparisons. You specify the names of the devices being measured, the tests performed, and each device's measurements for said test.
Graphs scale to meet the size of the end-user client display, and support mobile displays such as those rendered by the wptouch plugin.
Charts supported are horizontal bar, vertical bar, and pie. More can be added if desired.
PHP5 Required.
The shortcode format is:
[easychart argument="value" ...]
