Hi Andreas,
VOGIS is really nice regarding graphing profiles from surface elevation
datasets.
The use case here is  for viewing and editing profiles against 3D vector
data, not raster, such as water pipes for instance or geological data.
We chose to use a Canvas with all its power for styling and editing.
We think that we could head toward something in core in 3.0 for handling z
data, and merge raster samping over section lines, compared with 3D values
stored in vertex.
That would also be something really inline with multimap canvas proposal.

You can check public plugin prototype by vincent Mora here:

Cheers
Régis
