After saving the pdf with `savefigure()` and `bbox_inches='tight'` the colorbar is shifted.\r\nVery similar to bug #25176, which has already been fixed. \r\n\r\nThe problem only occurs when using the `bbox_inches='tight'` option in combination with `inset_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\nimport matplotlib.cbook as cbook\r\nimport matplotlib.cm as cm\r\nfrom matplotlib.patches import PathPatch\r\nfrom matplotlib.path import Path\r\nnp.random.seed(19680801)\r\ndelta = 0.025\r\nx = y = np.arange(-3.0, 3.0, delta)\r\nX, Y = np.meshgrid(x, y)\r\nZ1 = np.exp(-X**2 - Y**2)\r\nZ2 = np.exp(-(X - 1)**2 - (Y - 1)**2)\r\nZ = (Z1 - Z2) * 2\r\n\r\nfig, ax = plt.subplots()\r\nim = ax.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,\r\n               origin='lower', extent=[-3, 3, -3, 3],\r\n               vmax=abs(Z).max(), vmin=-abs(Z).max())\r\ncb = plt.colorbar(mappable=im)\r\nplt.show()\r\naxins = inset_axes(ax, width='20%', height='20%', loc='upper right')\r\nZ2 = axins.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,\r\n               origin='lower', extent=[-3, 3, -3, 3],\r\n               vmax=abs(Z).max(), vmin=-abs(Z).max())\r\nx1, x2, y1, y2 = -1,0,0,1\r\naxins.set_xlim(x1, x2)\r\naxins.set_ylim(y1, y2)\r\nrectpatch, connects = ax.indicate_inset_zoom(axins, edgecolor = 'k',alpha=1, lw = 1)\r\nconnects[0].set_visible(False)\r\nconnects[1].set_visible(True)\r\nconnects[2].set_visible(True)\r\nconnects[3].set_visible(False)\r\n\r\nfig.savefig(\"temp.pdf\",\r\n                bbox_inches='tight',\r\n                transparent=True,\r\n                format=\"pdf\")\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n[temp.pdf](https://github.com/matplotlib/matplotlib/files/13042716/temp.pdf)\r\n\r\n\r\n### Expected outcome\r\n\r\nSomthing like this:\r\n\r\n[temp.pdf](https://github.com/matplotlib/matplotlib/files/13042712/temp.pdf)\r\n\r\nbut with  tight layout\r\n\r\n### Additional information\r\n\r\nPython version : \r\nMatplotlib version: \r\n\r\n### Operating system\r\n\r\nOS: Linux Fedora 37 (Workstation Edition)\r\n\r\n### Matplotlib Version\r\n\r\n3.8.0\r\n\r\n### Matplotlib Backend\r\n\r\nmodule://ipympl.backend_nbagg\r\n\r\n### Python version\r\n\r\n3.11.5\r\n\r\n### Jupyter version\r\n\r\nmodule://ipympl.backend_nbagg\r\n\r\n### Installation\r\n\r\npip","author":{"url":"https://github.com/Hexanders","@type":"Person","name":"Hexanders"},"datePublished":"2023-10-19T12:48:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/27143/matplotlib/issues/27143"}
