Currently, this assumes that ticklabels are drawn horizontally, so rotating the tick labels can yield poor results.  It would be nice if ticklabel rotation (as set by tick_params) was taken into account in the computation.\n\n### Code for reproduction\n\n```Python\nfrom pylab import *; rcdefaults()\n\nfig = figure(figsize=(1.8, 1.8), layout=\"constrained\")\nax = fig.add_subplot(xlim=(0, 1), ylim=(0, 1))\n\nfig = figure(figsize=(1.8, 1.8), layout=\"constrained\")\nax = fig.add_subplot(xlim=(0, 1), ylim=(0, 1))\nax.tick_params(rotation=90)\n\nshow()\n```\n\n### Actual outcome\n\n\u003cimg width=\"180\" height=\"180\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/0df6d9cf-3737-4f3f-b85b-9a146c223230\" /\u003e\n\u003cimg width=\"180\" height=\"180\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/1c913ff4-9276-465c-ad0b-88a23e4932d3\" /\u003e\n\nThe first figure has reasonably spaced ticklabels; the second figure has too many yticklabels and (maybe) too few xticklabels.\n\n### Expected outcome\n\nIn the second plot ~3 yticks (at 0, 0.5, 1) and 5-6 xticks (every 0.2 or every 0.25).\n\n### Additional information\n\n_No response_\n\n### Operating system\n\nmacos\n\n### Matplotlib Version\n\n3.12.0.dev263+g0677cc8c1\n\n### Matplotlib Backend\n\nany\n\n### Python version\n\nPython 3.14.0\n\n### Jupyter version\n\nENOSUCHLIB\n\n### Installation\n\ngit checkout","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2026-07-06T21:14:44.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/32005/matplotlib/issues/32005"}
