So, I would like to use some custom fonts for my graphs in matplotlib. I was able to use the fonts following this post. 

import matplotlib as mpl
import matplotlib.font_manager as fm

path_font = 'D:\\myfonts\\'
font_dirs = [path_font + 'CustomSansPro\\', ]
font_files = fm.findSystemFonts(fontpaths=font_dirs)
font_list = fm.createFontList(font_files)
fm.fontManager.ttflist.extend(font_list)
mpl.rcParams['font.family'] = 'Custom Sans Pro'

However, in my custom fonts folder there are several types of font.
If I do: 

font_list:

I get something like: 

[<Font 'Custom Sans Pro' (CustomSansPro-Bold.ttf) normal normal 700 normal>,
<Font 'Custom Sans Pro' (CustomSansPro-Thin.ttf) normal normal 400  normal>,
<Font 'Custom Sans Pro' (CustomSansPro-LightItalic.ttf) italic normal 200 normal>,
<Font 'Custom Sans Pro' (CustomSansPro-BoldItalic.ttf) italic normal 700 normal>,
<Font 'Custom Sans Pro' (CustomSansPro-Medium.ttf) normal normal 500 normal>,
<Font 'Custom Sans Pro' (CustomSansPro-Light.ttf) normal normal 200 normal>,
...]

At present it I can just use one font type per font folder if I want to be sure that I am using a particular .tff. For example I would like to switch from Light.tff to LightItalic.tff to BoldItalic.tff.

How do I switch from one type to the other in my font list as they have all the same name (but different properties)?

Setting font.serif does not seem to have an effect.

  • Can you `print(font_dirs)` and post the output? – rustyshackleford Oct 16 '17 at 14:34
  • just the directory where my fonts are e.g. ['D:\\myfonts\\CustomSansPro\\'] – esperluette Oct 16 '17 at 14:37
  • Try changing `font_dirs = [path_font + 'CustomSansPro\\', ]` to `font_dirs = path_font + 'CustomSansPro\\'` – rustyshackleford Oct 16 '17 at 14:43
  • I tried, it does not to change anything. What I would like to do is to select the Bold or Thin types for example. As a workaround I could put each font in a separate folder but I think there is a better way of doing it! – esperluette Oct 16 '17 at 14:47
  • From the question it is not really clear whether you actually can use the `Custom Sans Pro` font, when importing it like you do. If this is the case, you may probably just need to additionally set something like `mpl.rcParams['font.weight'] = 'bold'` to get bold font and likewise for the other weights. – ImportanceOfBeingErnest Oct 16 '17 at 19:35
  • Yes, I can use it. But to be sure about which one I am using I need to have only one font file in the font folder (e.g. the file CustomSansPro-BoldItalic.ttf). I would like to keep all CustomSansPro fonts file in one folder and switch from 'Bold', 'Thin', etc. I tried the font.weight command but only 'normal' and 'bold' work. – esperluette Oct 17 '17 at 08:01
