When using `ax.set_xticks([])` (and/or yticks/rticks) the plot appears distorted. \n\n\n\n### Code for reproduction\n\n```Python\nimport numpy as np\nimport matplotlib.pyplot as plt\n\nD = np.array([[2,.3],[.3,2.5]])\n\n# creating an ellipse)\nlam, vec = np.linalg.eigh(D)\ntheta    = np.linspace(-np.pi,np.pi,1001)\nxy       = np.stack((lam[0]*np.cos(theta), lam[1]*np.sin(theta)), axis=0)\nxy       = vec.T@xy\nradii    = np.sqrt(np.sum(xy**2, axis=0))\nthetas   = np.arctan2(-xy[1],xy[0])\n\nplt.figure()\n# with ticks\nax1 = plt.subplot(121,projection='polar')\nax1.plot(thetas, radii)\n# without ticks\nax2 = plt.subplot(122, projection='polar')\nax2.plot(thetas, radii)\nax2.set_yticks([])\nax2.set_xticks([])\n\nplt.show()\n```\n\n### Actual outcome\n\n\u003cimg width=\"587\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/b6cb74b9-71ec-43c0-bc20-66c21bf2ff02\" /\u003e\n\n### Expected outcome\n\n\u003cimg width=\"380\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/ac204878-2602-46b4-82eb-3c9f43bb703a\" /\u003e\n\n### Additional information\n\n_No response_\n\n### Operating system\n\nOS/X and Linux\n\n### Matplotlib Version\n\n3.10.0\n\n### Matplotlib Backend\n\nmodule://matplotlib_inline.backend_inline\n\n### Python version\n\n3.10\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\nNone","author":{"url":"https://github.com/sjbabdi","@type":"Person","name":"sjbabdi"},"datePublished":"2025-06-11T12:56:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/30164/matplotlib/issues/30164"}
