Depending on where those ticks and labels were originally, and how the `top` ratio is set, labels will not go until the top of the y-axis, instead all the values appear with much less vertical spacing on the bottom part of the axis.\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nfrom mpl_toolkits.axisartist import SubplotHost\r\n\r\nfig = plt.figure(figsize=(25, 3))  # Originally setting a large enough height fixed our problem, but in this example it did not help\r\n\r\nax = SubplotHost(fig, 111)\r\nfig.add_subplot(ax)\r\n# ax = fig.add_subplot(111)  # using this produces the same outcome\r\n\r\ndata = [33.4, 33.5, 33.6]\r\n\r\nax.plot(data, data)\r\n\r\nticks = [32.8, 33., 33.2, 33.4, 33.6, 33.8]\r\n\r\n# Anomaly because labels won't match with ticks anymore if the next line is commented out\r\n# ax.set_yticks(ticks)\r\nax.set_yticklabels(map(str, ticks))\r\n\r\n# In this little example the bug is only triggered when the anomaly above holds\r\nfig.subplots_adjust(top=0.96)\r\n\r\nplt.show(dpi=300)\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n![image](https://github.com/matplotlib/matplotlib/assets/62675175/25301c6e-da1a-4b59-94fd-f5ffdfe2518a)\r\n\r\n### Expected outcome\r\n\r\n![image](https://github.com/matplotlib/matplotlib/assets/62675175/ab532afd-6802-40c7-8e7f-3c9ef8acfbef)\r\n\r\n\r\n### Additional information\r\n\r\nI suspect it depends on where those ticks and labels were originally, because we were also able to produce this bug where there was no mismatch required between labels and ticks.\r\nIt might also depend on the number of the top ratio being set.\r\nAs far as I know, adjusting other ratios (left, right, bottom, wspace, hspace) did not have an effect on this.\r\n\r\n### Operating system\r\n\r\nUbuntu 22.04\r\n\r\n### Matplotlib Version\r\n\r\n3.5.1\r\n\r\n### Matplotlib Backend\r\n\r\nagg\r\n\r\n### Python version\r\n\r\n3.9.12\r\n\r\n### Jupyter version\r\n\r\n_No response_\r\n\r\n### Installation\r\n\r\npip","author":{"url":"https://github.com/foldvaridominic","@type":"Person","name":"foldvaridominic"},"datePublished":"2023-07-27T08:27:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/26398/matplotlib/issues/26398"}
