===================================
Using a ttf font file in matplotlib
===================================
Although it is usually not a good idea to explicitly point to a single
ttf file for a font instance, you can do so using the
font_manager.FontProperties fname argument (for a more flexible
solution, see the font_family_rc.py and fonts_demo.py examples).
