[Paraview] Take spatial average on slice along a direction with a single filter

[Shuhao Wu]

Hello all,

What I want to do is to take a bunch of X slices in my domain and 
compute the average on that slice for a particular quantity. I want to 
then be able to plot this as a line plot (X vs average quantity) and 
also find the coordinate X of a specific average quantity.

I'm having trouble doing this in a single filter. Is this something that 
is supported? Right now my script is creating many slices and 
programmable filter (for averaging into a vtkTable) and then a 
programmable filter at the end combines all of the slices into a single 
vtkTable that I can use to plot. This can lead to hundreds of filters, 
which degrades performance drastically. I don't feel like this is the 
"correct" way to do things. Does anyone else know a better way?

Thanks,
Shuhao
