[Paraview] PV 4.10 plot over line using mesh coordinates

[Cory Quammen]

Hi Stephen,

To my knowledge there is no filter in ParaView to do what you are asking.
For an unstructured grid, it seems to me that no matter where the sample
points are on the line, you are going to need some kind of interpolation at
cell faces and edges where the line intersects the mesh structure to get
the data values to plot. For structured grids, you might be able to plot
values along a 1D subset of the mesh with some work, but not using the Plot
Over Line filter.

Thanks,
Cory
