[PATCH] Scale partial pressure graphs according to enabled gases

[subsurface at henrik.synth.no]

From: Henrik Brautaset Aronsen <subsurface at henrik.synth.no>

The max Y value of the partial pressure graph grid tends to be way too
high when only pO2 or pHe is enabled.

Ignore the previous patch, this one is better.
