Font "DejaVu Sans" can only be used through fallback #11077

Does Probably related to #10245 (due to the presence of a conda env, I guess). |
Nope, the problem is still here. The problem is also present using a fresh virtualenv created with: |

Can you provide the contents of your fontList.json? (perhaps via gist.github.com or other gist service, as it can be quite long) |
|
I can't reproduce this locally, even though I forced the use of your font cache. |

I do not know exactly what would be interesting to print, but this is what I tried. I added this at line 1215: print(best_font.fname)
print("Score:", best_score)
print("Family:", self.score_family(prop.get_family(), best_font.name))
print("Style:", self.score_style(prop.get_style(), best_font.style))
print("Variant:", self.score_variant(prop.get_variant(), best_font.variant))
print("Weight:", self.score_weight(prop.get_weight(), best_font.weight))
print("Stretch:", self.score_stretch(prop.get_stretch(), best_font.stretch))
print("Size:", self.score_size(prop.get_size(), best_font.size))
print('findfont: Matching %s to %s (%s) with score of %f' %
(prop, best_font.name, repr(best_font.fname), best_score))Then I ran the following code: import matplotlib as mpl
import matplotlib.pyplot as plt
mpl.rcParams['font.family'] = 'DejaVu Sans'
fig, ax = plt.subplots(figsize=(2,2))
ax.set_title('serif here as not expected', fontsize=20)
plt.show()OutputBut the displayed font is not correct: It seems to me that the font is correctly chosen at this step, so the problem is probably elsewhere. |

What happens if you edit backend_agg.py as follows: ? |
>>> import matplotlib as mpl
>>> import matplotlib.pyplot as plt
>>>
>>> mpl.rcParams['font.family'] = 'DejaVu Sans'
>>> fig, ax = plt.subplots(figsize=(2,2))
>>> ax.set_title('serif here as not expected', fontsize=20)
Text(0.5,1,'serif here as not expected')
>>> plt.show()Output |

I noticed that if I set Inputimport matplotlib as mpl
import matplotlib.pyplot as plt
mpl.rcParams['font.family'] = 'sans-serif'
mpl.rcParams['font.sans-serif'] = 'DejaVu Sans'
fig, ax = plt.subplots(figsize=(1,1))
ax.set_title('no serif here as expected')
plt.show()
print(ax.title.get_font_properties().get_fontconfig_pattern())Output
It makes me think that "DejaVu Sans" is not a valid If "DejaVu Sans" is truly not acceptable as a |

Well, as I mentioned earlier specifying "DejaVu Sans" for font.family does work for me and should work. |
|
Ok I think I got it, truly sorry if you lost time on this. The font I have been actually seeing this whole time was the default LateX font. With Example: import matplotlib as mpl
import matplotlib.pyplot as plt
mpl.rcParams['text.usetex'] = False
mpl.rcParams['font.family'] = 'DejaVu Sans'
fig, ax = plt.subplots(figsize=(1,1))
ax.set_title('sans serif here')
plt.show()
print(ax.title.get_font_properties().get_fontconfig_pattern())
With According to the comment in matplotlibrc, only a subset of fonts are supported with

OK, glad its working for you... |
Bug report
Bug summary
When
rcParams['font.family']is set to 'sans-serif', matplotlib correctly fallback to 'DejaVu Sans' (a warning is displayed and the "DejaVu Sans" font is plotted). However whenrcParams['font.family']is directly set to 'DejaVu Sans', matplotlib seems to use another font without warning.Code for reproduction
Actual outcome
Expected outcome
I would expect the font to be "DejaVu Sans" in both cases (i.e. without serif in both cases). It is possible that the warning message is, in fact, incorrect. But I can't find a way to display the font that is currently displayed on the graph.
Matplotlib version
print(matplotlib.get_backend())): TkAggMatplotlib was installed through conda (conda-forge channel).
Thank you.
