[Paraview] Changing Chart Series Visibilities from Python

[Greg Schussman]

Hi, Pat.

Here is an example that recreates the problem.  Using this as a CSV file:

AAA,BBB,CCC,DDD
0.0,1.0,2.0,3.0
0.0,2.0,4.0,8.0
0.0,3.5,2.5,1.5

and this (modified python trace) as a script run from the python shell 
in paraview:
----------------------------------------------------------------
try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

test_csv = CSVReader( FileName=['test.csv'] )

AnimationScene1 = GetAnimationScene()
RenderView1 = GetRenderView()
Delete(RenderView1)
SpreadSheetView1 = CreateRenderView()
SpreadSheetView1.ViewTime = 0.0

AnimationScene1.ViewModules = SpreadSheetView1

PlotData1 = PlotData()

XYChartView1 = CreateXYPlotView()
XYChartView1.ViewTime = 0.0

DataRepresentation2 = Show()
DataRepresentation2.XArrayName = 'AAA'
DataRepresentation2.AttributeType = 'Row Data'
DataRepresentation2.SeriesVisibility = ['vtkOriginalIndices', '0']

AnimationScene1.ViewModules = [ SpreadSheetView1, XYChartView1 ]

Render()

p = DataRepresentation2.SMProxy.GetProperty("SeriesNamesInfo")
series_names = [p.GetElement(i) for i in xrange(p.GetNumberOfElements())]
print "series_names:", series_names
----------------------------------------------------------------

I get back

   series_names: []

Thanks for any suggestions.

Greg
