"""
=============
Unicode minus
=============
You can use the proper typesetting Unicode minus (see
https://en.wikipedia.org/wiki/Plus_sign#Plus_sign) or the ASCII hyphen
for minus, which some people prefer. The matplotlibrc param
axes.unicode_minus controls the default behavior.
The default is to use the Unicode minus.

ax.plot(10*np.random.randn(100), 10*np.random.randn(100), 'o')
ax.set_title('Using hyphen instead of Unicode minus')
