The inner border is not in the correct place, it stays in the centre.\n\n### Code for reproduction\n\n```Python\nimport numpy as np\nimport matplotlib.pyplot as plt\n\nangles = np.radians(np.linspace(15, 145, 10))\nr = np.logspace(-30, -28, len(angles))\n\nfig = plt.figure()\nax = plt.axes(projection='polar')\n\nax.scatter(angles, r)\n\nax.set_theta_zero_location('N')\nax.set_theta_direction(-1)\nax.set_rscale('log')\nax.set_thetamin(15)\nax.set_thetamax(145)\n\nax.set_rorigin(10**-33)\n```\n\n### Actual outcome\n\n![Image](https://github.com/user-attachments/assets/e6e9d156-0c7f-4f39-aeca-551639ade884)\n\n### Expected outcome\n\n![Image](https://github.com/user-attachments/assets/d5768df8-c1ed-4fae-832b-ad226d7e515e)\n\nThe inner Border should look like this one.\n\n### Additional information\n\n_No response_\n\n### Operating system\n\nOS/X\n\n### Matplotlib Version\n\n3.10.3\n\n### Matplotlib Backend\n\nbackend_inline\n\n### Python version\n\n3.13.2\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\npip","author":{"url":"https://github.com/tillboehringer","@type":"Person","name":"tillboehringer"},"datePublished":"2025-06-15T17:09:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/30179/matplotlib/issues/30179"}
