Is there any plan to add a filter to Paraview to integrate variables over time? It seems like it should be a relatively simple thing to do.

PlotDataOverTime + a simple Programmable Filter should do the trick.

I supose IntegrateVariable could be improved to work with the output of PlotDataOverTime.

Feel free to open an issue on our gitlab to keep track of this need.
