Either provide the *cax* argument to use as the Axes for the Colorbar, provide the *ax* argument to steal space from it, or add *mappable* to an Axes.\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\n\r\nxs = np.random.rand(100)\r\n\r\n_, bin_edges, bars = plt.hist(xs)\r\ncolor_map = getattr(plt.cm, \"hot\")\r\nfor x_val, rect in zip(bin_edges, bars.patches):\r\n    rect.set_color(color_map(x_val))\r\n\r\ncbar = plt.colorbar(\r\n    plt.cm.ScalarMappable(cmap=color_map),\r\n    # cax=ax.inset_axes([0.95, 0.1, 0.05, 0.8]),\r\n)\r\n```\r\n\r\n### Actual outcome\r\n\r\nIn `matplotlib==3.6.0`:\r\n\r\n![mpl==3 6 0](https://user-images.githubusercontent.com/30958850/191547778-033472e7-e739-4beb-a1f4-eecdcb587e22.png)\r\n\r\n\r\n### Expected outcome\r\n\r\nIn `matplotlib==3.5.1`:\r\n\r\n![mpl==3 5 1](https://user-images.githubusercontent.com/30958850/191547733-cd4911a5-67c8-4070-a708-ce3399e8c0ba.png)\r\n\r\n### Operating system\r\n\r\nmacOS 12.6\r\n\r\n### Matplotlib Version\r\n\r\n3.6.0\r\n\r\n### Python version\r\n\r\n3.10\r\n\r\n### Installation\r\n\r\npip","author":{"url":"https://github.com/janosh","@type":"Person","name":"janosh"},"datePublished":"2022-09-21T15:37:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/23973/matplotlib/issues/23973"}
