I understand that there is no direct way of producing surface charts in LO Calc. There are surface chart workaround.ods like this. The existing functions for changing perspective, apperance and illumination are really neat. However, this is not the real thing as features like colorization by value range/elevation are missing.
Are there any other workarounds that I am not aware of yet?
Or is it better to use other software like gnuplot?
Is there enough interest to raise a feature request?
