The code works with Matplotlib 2.0.2.\r\n\r\nThe issue seems to be the combination of ``sharex=True, sharey=True`` and ``axis('equal')``.\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\nnrows = 3\r\nncols = 2\r\nfig, axes = plt.subplots(ncols=ncols, nrows=nrows, sharex=True, sharey=True)\r\n\r\nn = 20\r\nnp.random.seed(1234)\r\ndata = np.random.uniform(size=(nrows, ncols, n, n))\r\n\r\nfor i in range(nrows):\r\n    for j in range(ncols):\r\n        ax = axes[i, j]\r\n        ax.imshow(data[i, j])\r\n        ax.axis(\"equal\")\r\n\r\nplt.show()\r\n\r\n```\r\n\r\n**Actual outcome**\r\n\r\nWith Matplotlib 2.2.2, the figure is not drawn and the following exception is raised:\r\n\r\n```\r\nTraceback (most recent call last):\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\backends\\backend_qt5.py\", line 519, in _draw_idle\r\n    self.draw()\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\backends\\backend_agg.py\", line 433, in draw\r\n    self.figure.draw(self.renderer)\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\artist.py\", line 55, in draw_wrapper\r\n    return draw(artist, renderer, *args, **kwargs)\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\figure.py\", line 1475, in draw\r\n    renderer, self, artists, self.suppressComposite)\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\image.py\", line 141, in _draw_list_compositing_images\r\n    a.draw(renderer)\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\artist.py\", line 55, in draw_wrapper\r\n    return draw(artist, renderer, *args, **kwargs)\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\axes\\_base.py\", line 2546, in draw\r\n    self.apply_aspect()\r\n  File \"C:\\ProgramData\\Anaconda3\\lib\\site-packages\\matplotlib\\axes\\_base.py\", line 1631, in apply_aspect\r\n    raise RuntimeError(\"adjustable='datalim' is not allowed when both\"\r\nRuntimeError: adjustable='datalim' is not allowed when both axes are shared.\r\n```\r\n\r\n**Expected outcome**\r\n\r\nDrawn figure, no error, as with Matplotlib 2.0.2\r\n\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: Windows 7 64 bits\r\n  * Matplotlib version: 2.2.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): Qt5Agg\r\n  * Python version: 3.6\r\n  * Jupyter version (if applicable):\r\n  * Other libraries: Anaconda 5.2\r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\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/nbud","@type":"Person","name":"nbud"},"datePublished":"2018-06-11T16:16:57.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":14},"url":"https://github.com/11416/matplotlib/issues/11416"}
