Bug summary

Offset notation on the y-axis creates a "+1" or similar marker that overlaps a long title.

Code for reproduction

import matplotlib.pyplot as plt
import random
random.seed(123)
x = [n for n in range(100)]
y = [1 + random.random()/1000 for _ in range(100)]
fig, ax = plt.subplots()
ax.plot(x, y, '.-', label="random values near 1.0")
ax.set_title('abcdefghijklmnopqrstuvwxyz' + ' test ' + ' abcdefghijklmnopqrstuvwxyz')
ax.set_ylabel("y")
ax.set_xlabel("x")
ax.legend()
fig.savefig("example.png")
plt.show()

Actual outcome

example

Expected outcome

offset_notation_004

Additional information

There are workarounds such as passing arguments like y=1.03 or pad=15 to set_title() to push the title up manually. However, this should not be necessary as the documentation says "y is determined automatically to avoid decorators on the Axes" (see pull request #17127). Note also that setting constrained_layout=True does not change the output.

I thought we'd fixed this. Can you check 3.5.2? Thanks!

I can reproduce it on 3.5.1. Version 3.5.2 doesn't appear to be in Anaconda's repositories yet so I don't have an easy way to check it on my current machine.

Ok thanks for checking

I'll mark as a good first issue as this should be pretty straight forward addition to the current code that does this.

This is actually fixed by #22063, and will be in 3.6.0. Sorry about that @nnlnr.

Thanks @QuLogic I was pretty sure this had been fixed, but couldn't find the PR, and forgot to check master...
