The basic setup including a twin Axes is done once and the Axes are cleared at the end of the loop using `cla()`.  \r\n\r\n`Axes.cla()` resets the label position of the `yaxis` of the twin Axes to the default (left), resulting in misplaced ylabels in all but the first loops.  \r\n\r\nTicks and tick labels of the left y axis are kept at the correct side, so I would the axis label also expect to be kept at the correct side.\r\n\r\n### Code for reproduction\r\n\r\n```Python\r\nimport matplotlib.pyplot as plt\r\n\r\nfig, ax1 = plt.subplots()\r\nax2 = ax1.twinx()\r\nfor i in range(2):\r\n    # do some plotting here\r\n    ax2.set(ylabel=f'ylabel of plot # {i}', ylim=(1, i + 2))\r\n    fig.savefig(f'{i}.png')\r\n    ax1.cla()\r\n    ax2.cla()\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n**1.png:**\r\n\r\n![1](https://github.com/user-attachments/assets/f41d9cb4-b564-4480-b1f3-76d9b95c38f3)\r\n\r\n\r\n### Expected outcome\r\n\r\nThe expected outcome was produced by adding `ax2.yaxis.set_label_position('right')` to the loop:  \r\n\r\n![1](https://github.com/user-attachments/assets/7970837a-71a3-4278-9afc-3f17ab7559a5)\r\n\r\n\r\n### Additional information\r\n\r\n_No response_\r\n\r\n### Operating system\r\n\r\n_No response_\r\n\r\n### Matplotlib Version\r\n\r\n3.9.2\r\n\r\n### Matplotlib Backend\r\n\r\n_No response_\r\n\r\n### Python version\r\n\r\n_No response_\r\n\r\n### Jupyter version\r\n\r\n_No response_\r\n\r\n### Installation\r\n\r\nNone","author":{"url":"https://github.com/StefRe","@type":"Person","name":"StefRe"},"datePublished":"2024-09-19T16:32:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/28846/matplotlib/issues/28846"}
