Right, most fonts do not provide sans-serif math-mode fonts. And the
ticklabels are always rendered in math mode, such that minus signs are
rendered as minus signs (and not hyphens). That may seem like a minor issue,
but having hyphens for minus signs on a linear x-axis and regular minus signs
on a log y-axis doesnt look professional.

We tried supporting sans-serif ticklabels with usetex a while back, and it
turned out to be a headache. I'll have a look at cmbright, but no promises.
