[Paraview] Re: extract probe data

[David E DeMarle]

In the probe filter's csv output, the X/T coordinate is the distance 
along the sampling line. This is not the same thing as the X dimension 
in the visualization unless the line happens to starts at X=0 and is 
parrallel to the X axis. You likely just need to remember that X/T means 
Y or Z in your case, dependending on how you've oriented the probe line.

----

Berk and Utkarsh are correct, we should add something that copies 
geometry to attribute data in ParaView to make the probe's output more 
explicit.

----

If you analyze the exact X, Y and Z values along with your attribute 
data immediately you can try something completely different:

1) use two orthogonal cut planes to define your cut line
2) save data into a legacy vtk file
3) run the following vtk script to convert to ascii to make life easier

vtkDataSetReader r
r SetFileName "binary.vtk"
vtkDataSetWriter w
w SetFileName "ascii.vtk"
w SetInput [r GetOutput]
w Write
exit

4) match up the Points with the Scalars in your favorite editor, 
spreadsheet or scripting language.

cheers,
Dave DeMarle
