When hovering stacked bars, absolute Y values are passed in DataPoint #51

Closed GoogleCodeExporter closed 8 years ago

Hover a stacked bar chart. If you have three bars stacked on top of each other 
and you hover the top most bar, then the item that is passed to onPlotHover() 
returns an absolute Y value when you call item.getDataPoint.getY(). Instead it 
should (additionally) provide me with the relativ Y value (the height of the 
bar segment).
When adding the DataPoints to the Model I provide the correct Y value, but in 
onPlotHover() I get the Y sum of all segments up to the one I hovered.
This behaviour is not useful as one normally wants to show the value of the 
hovered bar segment.

Try this :
item.getSeries().getData().getY( item.getDataIndex() )

series.getData() method isn't public.
