To setup

Answer 1

Solved the problem like this:

import matplotlib.font_manager as font_manager

font_dirs = ['/my/custom/font/dir', ]
font_files = font_manager.findSystemFonts(fontpaths=font_dirs)
font_list = font_manager.createFontList(font_files)
font_manager.fontManager.ttflist.extend(font_list)

mpl.rcParams['font.family'] = 'My Custom Font'

The fontpaths kwarg can also be a string in case you only have a single directory to import from.
