Hi All,

I have data defined on a surface mesh (of triangles). I can slice it with a plane and I can now see the data as a color plot on a polyline in the 3D viewer. How can I see the data as an XY plot with the X axis being the arc-length and the Y axis being the data?

I am sure this would be a “tricky” filter as there could be multiple, separated polylines with branching. But it appears that developers in ParaView were planing to add this at some point in the past:

This is a page from 2009.

Thanks in advance,

Gonzalo
