This plugin allows you to easily insert charts into your blog, by way of shortcodes. While multipurpose, the chart system is intended to make it easy for posting detailed review measurements of some sort, such as poll data, video card comparisons, sports scores, etc. You specify the names of the devices being measured, the tests performed, and each device’s measurements for said test.
An admin settings page allows you to tailor many shortcode defaults, simplifying overall use.
The shortcode is supported on posts, pages, and in widgets.
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, stacked horizontal bar, vertical bar, stacked vertical bar, line graph, and pie. More can be added if desired.
PHP5 Required.
The shortcode format is:
[easychart argument=”value” …]
