Description
Toggling the visibility of the axis tick labels via set_visible(False) can lead to their outright destruction, see here. According to @ImportanceOfBeingErnest, this issue is related to #10088.
I include a minimal code fragment that demonstrates the problem.
Code for reproduction
from matplotlib import pyplot as plt
plt.plot([0, 1], [8, 6])
ax = plt.gca()
yticks = ax.get_yticklabels()
print(yticks)
for tick in yticks:
tick.set_visible(False)
print(ax.get_yticklabels())Actual outcome
<a list of 11 Text yticklabel objects>
<a list of 0 Text yticklabel objects>
Expected outcome
The snippet shows that the y tick labels are destructed after setting their visibility to False. One can restore them by issuing:
ax.yaxis.set_tick_params(labelleft=True)
This issue first occurred on matplotlib 3.1.2 but not on the previous version (which I believe was 3.0.x).
Matplotlib version
- Operating system: Win10 Pro 64bit
- Matplotlib version: 3.1.2
- Matplotlib backend (
print(matplotlib.get_backend())): Qt5Agg - Python version: 3.6.3
Python was installed via WinPython; Matplotlib was manually upgraded to v3.1.2.
