[Paraview] Selecting a point in Python

[Cory Quammen]

HI Alan,

Selections are indeed possible in Python, though as you have found they are
not recorded in traces.

You should be able to do something like this to select one or more points:

can = GetActiveSource()


# Extract the desired block first

extractBlock = ExtractBlock(Input=can)

extractBlock.BlockIndices = [2]


# Now extract point 1764

pointID = 1764

pointIDs = [0, pointID] # process number, point ID

selection = paraview.simple.IDSelectionSource(ContainingCells=0, FieldType
= "POINT", IDs = pointIDs)
plotSelectionOverTime1 = PlotSelectionOverTime(Input=can,
    Selection=selection)

qcv = CreateView('QuartileChartView')

d = Show(plotSelectionOverTime1, qcv)


I hope this helps,

Cory
