[Paraview] Changing Chart Series Visibilities from Python

[Greg Schussman]

Hi, Pat.

On further checking, there's still some sort of problem.

When I use your example below, it works in ParaView's Python Shell, if 
the PlotData filter was created via the ParaView gui.   However, if it 
was created in the macro (using the text from a python trace of how it 
was created via the gui), then your example produces an empty list.   
The PlotData filter created in the macro does show up on the screen and 
look correct; but the series names aren't accessible.

Does this provide any useful clues?

Thanks.

Greg
