My guess is that a circular scale is programmable
here, but that there is no way that any existing
official Stata call will produce what you want.
-galbr- doesn't seem to have been updated
since STB-56. The following is a fairly free
translation that should not be blamed on Aurelio
Tobias. It doesn't bear a circular scale.
