Bug summary
This possibly related to #20738
When I run the code below on a new jupyter kernel, only the tick styling is working. The figure.size and figure.dpi is ignored first.
One has to run something interacting with the backend first (like matplotlib.pyplot.show() ) in order to get plt.rc_context() working correctly.
Is this normal behavior, since the correct backend already seems to be activated or did I oversee something?
Code for reproduction
import matplotlib.pyplot as plt
rc = {"figure.figsize": [6, 1], "figure.dpi": 150, "xtick.direction": "in", "ytick.direction": "in"}
# Uncommenting this helps, but is this the intended behavoiur in jupyter?
# plt.show()
with plt.rc_context(rc):
# Sanity check.
print(f"{plt.rcParams['figure.figsize']=}")
print(f"{plt.rcParams['figure.dpi']=}")
print(f"{plt.rcParams['backend']=}")
fig, ax = plt.subplots()
# ax.plot(x, x)
plt.show()Actual outcome
plt.rcParams['figure.figsize']=[6.0, 1.0]
plt.rcParams['figure.dpi']=150.0
plt.rcParams['backend']='module://matplotlib_inline.backend_inline'
Expected outcome
Runnig the code twice, which has then plt.show() already called once delivers the correct output:
