The chart editor data and script tabs did not work correctly when one or more plots were disabled.
5.13 23 August 2017 You can now add a CSV download option to charts and Google tables, but you also need version 5.06 of the plugin for this to work.
There's a new Plotalot variable: %%J_CURRENT_DATE%%
Fix for a PHP notice error when running the Smart Search Indexer plugin and error reporting is on. Fix for a rare character encoding issue in Plotalot tables.

The About page now shows the Plotalot Plugin status, if it is installed.
Re-coding of deprecated Joomla functions, in preparation for future Joomla versions. The minimum Joomla version required is now 3.4.8.

The component now supports executing the extra Javascript every time the plugin refreshes the chart.

5.08 24 November 2016 Fix for a bug introduced in 5.05: If a plot of a multi-plot chart returned no rows, the chart generated an error for the empty plot instead of ignoring the empty plot and drawing the remaining plots.
5.07 22 November 2016 Fixed a bug that caused the install script to crash in some situations.
5.06 14 November 2016 Supports entry of the purchase ID (on the About page) for the Plotalot Plugin, enabling fully automatic updates of the Plugin. You'll need the latest version of the Plugin to take advantage of this feature.
Fix for incorrect handling of the Joomla tmp directory on Windows, where the tmp directory had an upper-case drive letter.
Fix for "Undefined offset" notice error if a Combo chart with a candlestick plot had less than 4 columns.
5.05 2 November 2016 There are no longer separate versions of the free and paid component (all the paid functions are in the plugin), and the X axis title restriction in the free version has been removed.
The component now supports the Joomla Update System. The Joomla admin interface notifies you of new releases, and you can install them with a single click in the Extensions Update Manager.
There is now an Extra Javascript field, giving the ability to support formatters and many other advanced features. See the latest user guide for an example.
Combo charts can now include candlestick plots, and can now hide individual legend entries.
Two minor bug fixes: The chart title colour was not saved; And in some cases when a plot returned no rows the error shown was "No plots enabled" when it should have been "No rows". These have both been fixed.
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.
5.03 22 March 2016 Fixed a warning that occurred when running on PHP 7.
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).
