[vtkusers] Colors in BarPlot

[Darshan Pai]

Just to add to the previous question.

For the vtkPlotPoints I have a color array which is connected to the
category array .
I have added a functionality where depending on the category that was
selected, I make the selected category as a opaque point, where the others
are transperant. My issue is the tooptip will show the blanked points value
too .
Now I know that I need to change some event handler, but not sure which one
is this . Can anyone help ? I do not even know whether if I subclass
vtkPlotPoints , what is it I change.

Regards
Darshan
