===================================
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.

Here, we use the Computer Modern roman font (``cmr10``) shipped with
Matplotlib.

For a more flexible solution, see :doc:`/gallery/api/font_family_rc_sgskip` and
:doc:`/gallery/text_labels_and_annotations/fonts_demo`.
