Computer Modern Glyph Error #17007
Description
Bug report
Trying to use computer modern roman (cmr10) font in plot. Getting an error which prevents minus sign rendering in plot.
import matplotlib as mpl
import matplotlib.pyplot as plt
mpl.rc('font',family = 'serif', serif = 'cmr10')
fig, ax = plt.subplots()
ax.set_title('This is a special font:')
ax.set_xlabel(r'This is the default font $\alpha\beta\gamma$')
ax.set_yticks([-1,0,1])
plt.show()
Output:
C:\ProgramData\Anaconda3\lib\site-packages\matplotlib\backends\backend_agg.py:214: RuntimeWarning: Glyph 8722 missing from current font.
font.set_text(s, 0.0, flags=flags)
C:\ProgramData\Anaconda3\lib\site-packages\matplotlib\backends\backend_agg.py:183: RuntimeWarning: Glyph 8722 missing from current font.
font.set_text(s, 0, flags=flags)
