The SmartLegend extension

SmartLegend is an extension which implements the chart legend with a more advanced behavior, developed by Alexander Tokarev. This extension class is basically the same as Ext.chart.Legend, except that some of its methods were refactored for a better re-use.

Following is the screenshot of a chart where the SmartLegend extension is used:
