RE: [jCharts-users] getting index of a value in a dataset from Av isValueRenderEvent

[Lapinski, M. (Research) <lap...@cr...>]

yes, I realize that the data setindex will always be 0 into the array of
datasets, what 
I was looking for is the index of the current array item in the dataset[0]
array. So as 
below int dataSetIndex = avre.getDataSetIndex(); is always 0,



What I am looking for is to be able to getthe index value for a call to
acd.getValue(int dataset,
 int index). I can hardcode the size of the graph and then user the
getValueX() pixel locations 
and cobjob to get the index of what bar is beign rendered, but I would
rather have it be more 
flexible. Please let me know if there is any way to do this or if I have to
go the static route.


-thank you

For a BarChart, the index will allows be zero as there is only one dataset.
Please note, those RenderEvents are not enabled on any chart with more than
one dataset yet. (ie Clustered or Stacked
Bars)
