[Paraview] no probe over line output with paraview scripting

[m.c.wilkins at massey.ac.nz]

Hi Utkarsh,

Thanks, I am using 3.9, but I wasn't using paraview.simple, just
following the examples in the Python Scripting chapter in the ParaView
Guide.  Using paraview.simple does make things simpler ;-)  and indeed
I can get it to work.

For the record this works fine for me:

from paraview.simple import *
reader = servermanager.sources.XMLUnstructuredGridReader(FileName = "/var/tmp/file.vtu")
pl = PlotOverLine(Input = reader)
pl.Source.Point1 = [-7000, -5000, 0]
pl.Source.Point2 = [4300, 6300, 1111.75]
CreateXYPlotView()
d = Show()
d.XArrayName = 'arc_length'
d.SeriesVisibility = ['namecolours (0)', '0', 'namecolours (1)', '0', 'namecolours (2)', '0', 'vtkValidPointMask', '0', 'arc_length', '0']
d.UseIndexForXAxis = 0
Render()

OK, so got past this problem, more to come I expect!

Thank you

Matt Wilkins
