Feel free to provide a minimal verifiable example, which allows to reproduce the probem. Else, I see little chance to help here.

Try increasing your dpi on the png.

There is some weird dpi-dependent code for adding or dropping ticks. One of my prs fixes it though I’m not sure if it’s been merged yet. EDIT: Not merged: #12158

It is indeed related to the DPI I set. But it is the other way around you suggested. Up to 80 DPI everything is fine. Above that, the tick labels are pruned. Weird. I would try to come up with a reproducible example.

You probably don't need to - its a known issue... From my testing, I think its an issue of your upper ylimit limit being close, but less than, 1.25. When you decrese the dpi, your upper limit becomes within 1/2 a pixel of 1.25 and includes the 1.25; when you increase the dpi your upper limit is no longer within 1/2 a pixel, and it gets trimmed.

#12158 will always trim that tick because your upper y-limit < 1.25. Of course, if you manually specify set_ylim([0, 1.25]) it will not be trimmed. I think that is the correct and consistent behaviour.

A minimal example is:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set_ylim(0, 1.199)

fig.savefig('boo100.png', dpi=100)
fig.savefig('boo200.png', dpi=200)

Thank you. That worked.
