New Profile: make axis labels smaller

Previously all text in the new profile was deawn in the same font. With
this change the labels on all axes are smaller.
It might be even better to allow per-axis configuration of the label size
as along the time axis the bigger size looked better. But especially for
partial pressures this looks much better.
