This was supposed to be a feature not a bug. As far as I understand,
we are now using the proper minus sign which has the same width as the
horizontal part or a plus sign. See
http://en.wikipedia.org/wiki/Plus_sign#Plus_sign
in the section "Character codes". The hyphen, which doubles as a
minus sign in the ascii character set, is not the proper character for
typesetting.
I don't think this is the problem Nils is having, because the
character code for the minus sign is different (and in the formatter,
we explicitly convert this if usetex is True) in the
ScalarFormatter.fix_minus method.
If the unicode minus is sufficiently problematic for you, I can add an
rc param. Something like
axis.unicode_minus : True
The problem here appears to be in
matplotlib.projects.polar.ThetaFormatter.__call__, which uses the
degree symbol. I think all we need to do is return the proper tex
string in this case. Michael, does this look right to you:
def __call__(self, x, pos=None):
# \u00b0 : degree symbol
if rcParams['text.usetex'] and not rcParams['text.latex.unicode']:
return r"$%d^\circ$" % ((x / npy.pi) * 180.0)
else:
return u"%d\u00b0" % ((x / npy.pi) * 180.0)
