OnClickListeners() for all Graphs

[Sheharyar Naseer]

Your graphs are beautiful, but they are not interactive. Not only that, many apps depend on the interaction with charts. I propose to add OnClickListeners() and SetOnClickListeners() for "Points in LineGraphs", "Bars in BarGraphs" and "Slices in PieCharts".

These do actually already exist. Take a look at the sample code.
