[Paraview] Selecting a point in Python

[Cory Quammen]

Alan,

Oops, clicked 'Send' too fast. You don't really need the extract block
part. Try this instead:

can = GetActiveSource()

pointID = 1764

pointIDs = [0, pointID] # process, id

selection = IDSelectionSource(ContainingCells=0, FieldType = "POINT", IDs =
pointIDs)

plotSelectionOverTime1 = PlotSelectionOverTime(Input=extract,

    Selection=selection)

qcv = CreateView('QuartileChartView')

d = Show(plotSelectionOverTime1, qcv)


Thanks,

Cory
