[Paraview] plotting integrated values of cutting plane at various offsets

[Eric E. Monson]

Could you be a bit more clear about what you're trying to do? It sounds like you're trying to take your contours and integrate some attributes over each of the contours separately so you get a table which contains as many rows as the number of contours (and maybe separate columns for each attribute)?

As I was playing around I had trouble creating a programmable filter which has a polygonal mesh as input, but a vtkTable as output... Does anyone know if this is possible? Or, does vtkDataObjectToTable filter exist for ParaView so the data could be run through that before the programmable filter?

If I'm understanding what you're trying to do, it seems like it should be possible to implement with a programmable filter if this piece can be accomplished, even without the Integrate Attributes filter.

In filters.xml it show as being called vtkIntegrateAttributes but I cannot create this in python.  Also, there is no webpage for this class on the nightly documentation site.

This would build up a list (in a polydata or vtkTable for example) which could then be plotted on a graph. A reset button on a custom panel can be used to clear the values. I’ve done this a couple of times for time related filters when I wanted to plot something unusual over T.
