Joomla 3.x versions
Version Date Changes
5.04 17 April 2016 Fix for a bug that prevented auto-refresh working properly for charts with date axes. Unfortunately this also required a change to the plugin. For auto-refresh to work properly with date axes, you must have (at least) version 5.04 of the component AND (at least) version 5.01 of the plugin. Note that there is no free version of 5.04 since the free version does not handle auto-refresh.

5.02 1 February 2016 The Y format selector can again be used to format the numeric values for pie charts (broken since 4.01).
