Bug report

Bug summary

I know that Matplotlib does not officially support OpenType fonts, but I have successfully been using them for axis labels in version 1.5.3 and earlier. I just updated Matplotlib via Macports and the character spacing and alignment broke, especially with larger font sizes. For example, X axis titles that are centered begin at the same position, but have extra wide spacing. This is found with all OpenType fonts that I have tried.

Code for reproduction

• This requires the free font Canter (not ideal for graphing, but it is available for testing), but can be reproduced with other fonts.
• I have only included my setting of the fonts and saving the PDF, as this can be reproduced with any plot I've made.

import matplotlib as mpl
import matplotlib.pyplot as plt
f = {'family':'Canter;, 'weight':'light', 'size':20}
mpl.rc('font', **f)

plt.savefig('test.pdf', transparent=True)

Actual outcome

170208-correlation-version 2.pdf

Expected outcome

170208-correlation-version 1.5.pdf

• This worked in v 1.5.3 and does not work in 2.0.0

Matplotlib version

• Python 2.7, Matplotlib versions 1.5.3 and 2.0.0, installed via macports
