[vtkusers] selecting scalars in vtkXMLPolyDataReader

[Keyan Mehravaran]

Hello,

I have created a vtkXMLPolyData (miraculously works in paraview), and I'm reading it vtkXMLPolyDataReader().
I feed the reader to a polydata:
PD = vtk.vtkPolyData()
PD = reader.GetOutput(),
which successfully reads the file with all the cells, points, scalars, vectors.
Now, I would like to select, say the 5th array of points, and paint it (the data are on  a plane). I would highly appreciate your help in directing me towards the solution. I am attaching the output of "print PD", below.

Best Regards,

Kian Mehravaran
