But _update_patch_limits still uses these points in updating the data limits. patches.Wedge creates such points that are outside the region of the patch.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug.\r\nPlease make sure to minimize the number of dependencies required, and provide\r\nany necessary plotted data.\r\nAvoid using threads, as Matplotlib is (explicitly) not thread-safe.--\u003e\r\n\r\n```python\r\nfrom matplotlib import patches\r\nfrom matplotlib import pyplot\r\n\r\nf = pyplot.figure()\r\na = f.add_subplot()\r\na.add_patch(patches.Wedge((0,-1.0),1.05,60,120,0.1))\r\na.relim()\r\na.autoscale_view(True)\r\nf.show()\r\n```\r\n\r\n**Actual outcome**\r\n\r\n\u003c!--The output produced by the above code, which may be a screenshot, console output, etc.--\u003e\r\n![201207a](https://user-images.githubusercontent.com/24276120/101403746-aa204b80-38a3-11eb-8253-cd1ee3c4872b.png)\r\n\r\n```\r\n# If applicable, paste the console output here\r\n#\r\n#\r\n```\r\n\r\n**Expected outcome**\r\n\r\n\u003c!--A description of the expected outcome from the code snippet--\u003e\r\nThe lower limit of the y axis should not be so far from the actual painted region.\r\n\u003c!--If this used to work in an earlier version of Matplotlib, please note the version it used to work on--\u003e\r\n\r\n**Matplotlib version**\r\n\u003c!--Please specify your platform and versions of the relevant libraries you are using:--\u003e\r\n  * Operating system: Arch Linux\r\n  * Matplotlib version: 3.3.3\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): Qt5Agg\r\n  * Python version: 3.9.0\r\n  * Jupyter version (if applicable):\r\n  * Other libraries: \r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\r\nInstalled via pacman\r\n\u003c!--If you installed from conda, please specify which channel you used if not the default--\u003e\r\n\r\n","author":{"url":"https://github.com/jsberg-bnl","@type":"Person","name":"jsberg-bnl"},"datePublished":"2020-12-07T20:55:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/19078/matplotlib/issues/19078"}
