How to load .ttf file in matplotlib using mpl.rcParams?
fonts, matplotlib, python
Solution
Specifying a font family:
If all you know is the path to the ttf, then you can discover the font family name using the `get_name` method:
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager
path = '/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
prop = font_manager.FontProperties(fname=path)
mpl.rcParams['font.family'] = prop.get_name()
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', size=40)
plt.show()
Specifying a font by path:
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager
path = '/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
prop = font_manager.FontProperties(fname=path)
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', fontproperties=prop, size=40)
plt.show()
Problem
I have a matplotlib script that starts ... ``` import matplotlib as mpl import matplotlib.pyplot as plt import matplotlib.font_manager as fm mpl.rcParams['xtick.labelsize']=16 ... ``` I've used the command ``` fm.findSystemFonts() ``` to get a list of the fonts on my system. I've discovered the full path to a .ttf file I'd like to use, ``` '/usr/share/fonts/truetype/anonymous-pro/Anonymous Pro BI.ttf' ``` I've tried to use this font without success using the following commands ``` mpl.rcParams['font.family'] = 'anonymous-pro' ``` and ``` mpl.rcParams['font.family'] = 'Anonymous Pro BI' ``` which both return something like ``` /usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1218: UserWarning: findfont: Font family ['anonymous-pro'] not found. Falling back to Bitstream Vera Sans ``` Can I use the mpl.rcParams dictionary to set this font in my plots? EDIT After reading a bit more, it seems this is a general problem of determining the font family name from a .ttf file. Is this easy to do in linux or python ? In addition, I've tried adding ``` mpl.use['agg'] mpl.rcParams['text.usetex'] = False ``` without any success
