I have linestring geometries with z values and I want to display them in a nice elevation profile (with x/z scaling functions, several profiles to overlay, and so on).
Is there any QGIS function or plugin for it?
I've seen tools for digitizing elevation profiles from DEM's, e.g. Profile tool. These tools have such a height profile display, but they seem to require the height digitization I don't need.
I could go to Excel, yes. But I'd like to stay inside QGIS in order to avoid another interface.
