Hi I am trying to display a depth bar on the extended profile that starts from 0. Not to show the altitude, but only the depth of the cave relative to the entrance. This is not a problem if I use the FIX command like: centerline cs long-lat fix 1 11:22:33.3 22:33:44.4 1000 # fix point 1to the WGS coordinates and altitude The thing is that I don't want to put 0 for an altitude because it seems useful to have the real altitude for some 3D, overlays, etc So I would like to use FIX with the altitude, but on the extended to see the cave depth starting from 0. I tried with some combinations of grid-origin like this, but I still see the altitude in the depth bar: layout xelev grid bottom cs long-lat grid-origin 0 0 0 m Is there a way to do it?
