I am currently using ParaView for post-processing while developing a solver as part of my master’s studies. In my code, the output is generated as rectilinear cells—so my data is in the form of cell data. When I apply the “Cell Centers” filter followed by the “Plot Over Line” filter, ParaView crashes. So far, it has consistently crashed every time I follow this sequence. My paraview version is 5.13.1. But if Im not mistaken, this problem exists in latest version aswell.

I confirm that ParaView crashes with the PlotOverLine filter when there is no cells in a dataset, please open an issue: [https://gitlab.kitware.com/paraview/paraview/-/issues](https://gitlab.kitware.com/paraview/paraview/-/issues)

Arguably, cell centers should generate at least a polyvertex, but that a much less important issue.
