Bug report
Bug summary
The '\times' glyph in minor ticklabels of log plots is not being recognized because it is getting wrapped inside '\mathdefault{...}'. The problem and a temporary solution (simply removing '\mathdefault') is fully described on Stack Overflow.
Code for reproduction
import matplotlib
import matplotlib.pyplot as plt
# Customize matplotlib
matplotlib.rcParams.update({# Use mathtext, not LaTeX
'text.usetex': False,
# Use the Computer modern font
'font.family': 'serif',
'font.serif': 'cmr10',
'mathtext.fontset': 'cm',
# Use ASCII minus
'axes.unicode_minus': False,
})
# Plot
plt.semilogy([-0.03, 0.05], [0.3, 0.05])
plt.savefig('test.png')Actual outcome
python/lib/python3.6/site-packages/matplotlib/mathtext.py:866: MathTextWarning: Font 'default' does not have a glyph for '\times' [U+d7]
MathTextWarning)
python/lib/python3.6/site-packages/matplotlib/mathtext.py:867: MathTextWarning: Substituting with a dummy symbol.
warn("Substituting with a dummy symbol.", MathTextWarning)
Expected outcome
This is only a problem with matplotlib 2.x, as 1.x never automatically places minor ticklabels.
Matplotlib version
- Operating system: Linux
- Matplotlib version: 2.0.2, but the bug is consistently reproduced in all of matplotlib 2.x
- Matplotlib backend: Agg, TkAgg
- Python version: 3.6
I have installed Python and matplotlib from source.
