Simple plot spacing bug: ylabel gets wrongfully removed from plot

[Volker-Weissmann]

Bug report

Bug summary

Matplotlib removes part of the plot

Code for reproduction

import matplotlib.pyplot as plt
plt.ylabel("yLabel")
x = [1,4]
n = -4 #bug occurs if n is -4, -5 -6, or 6
y = [1*10**n, 4*10**n]

plt.plot(x,y, "r+")
plt.show()

Actual outcome

As you can see: The ylabel is partly missing

Expected outcome

There should be a "yLabel" written on the y-Axis.

Thats why things like constrained_layout and tight_layout are necessary. By default, the axes only makes enough room for "normal" labels, but yours have a lot of decimal places, so the label is off the plot.

plt.figure(constrained_layout=True)

plt.figure(tight_layout=True)

or
plt.savefig(bbox_inches='tight')

are the ways to handle this sort of problem.

Closing because there is nothing automatic we can do to fix this.

Sorry, I did not know that these options exist. Thank you for your help.
