I am a newbie to Paraview and have little experience programming Python.  I 
would like to know how to call a particular filter from within Python.  The 
only filter I have seen referenced in the Python scripting documentation is 
Shrink().

I want to retrieve the scalar values along a line segment (Plot Over 
Line(ProbeLine)) that extends through an unstructured 3D grid.  I have "The 
ParaView Guide", "The VTK User's Guide" and "The Visualization Toolkit:  An 
Object-Oriented Approach to 3D Graphics".  I don't see how to programmatically 
do this.  I have looked on all of the ParaView web sites that I can find, and 
in tutorials.  I do not even see a list of available filter names.

Is there a guide for Python Scripting (chapter 20 of The ParaView Guide is the 
best I have found) that covers using filters?  Example code?  Anything?  How 
do you even find the filter names in the documentation?

Thanks for any help,
Hamilton Woods
