The change bisects to #28393.\r\n\r\n### Code for reproduction\r\n\r\n```Python\r\nimport datetime\r\n\r\nimport numpy as np\r\nimport matplotlib.pyplot as plt\r\n\r\ndts = [datetime.datetime(2009, 9, 9, 17, 0) + datetime.timedelta(minutes=n) for n in range(10, 61, 10)]\r\nfoo = range(5)\r\ndata = np.arange(30).reshape(6, 5)\r\n\r\nplt.contourf(foo, dts, data)\r\nplt.show()\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n![image](https://github.com/user-attachments/assets/4f616f86-14d7-4335-b0c1-e5dfc637cdbc)\r\n\r\n\r\n### Expected outcome\r\n\r\nBefore #28393 I get\r\n![image](https://github.com/user-attachments/assets/e9dc1e03-2945-428b-bb71-eceb1114f5d4)\r\n\r\n\r\n### Additional information\r\n\r\n_No response_\r\n\r\n### Operating system\r\n\r\nUbuntu\r\n\r\n### Matplotlib Version\r\n\r\nv3.9.1 and `main`\r\n\r\n### Matplotlib Backend\r\n\r\n_No response_\r\n\r\n### Python version\r\n\r\n3.12\r\n\r\n### Jupyter version\r\n\r\n_No response_\r\n\r\n### Installation\r\n\r\nconda","author":{"url":"https://github.com/rcomer","@type":"Person","name":"rcomer"},"datePublished":"2024-07-13T20:32:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/28567/matplotlib/issues/28567"}
