(not sure how to phrase this; see below)\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug, also minimizing the number of dependencies required--\u003e\r\n\r\n```python\r\nf, ax = plt.subplots(2,2, constrained_layout=True)\r\n\r\ndata = np.random.randn(10, 10)\r\n    \r\nfor aa in ax.flat:\r\n    mappable = aa.pcolormesh(data)\r\n    \r\nf.colorbar(mappable, ax=ax[:, 0])\r\n```\r\n\r\n**Actual outcome**\r\n\r\n![image](https://user-images.githubusercontent.com/2448579/42615612-3335ec1e-8568-11e8-9424-dcd4002ed92b.png)\r\n\r\n**Expected outcome**\r\n\r\nI would like the constrained_layout version of this --- which results when setting `constrained_layout=False` in the `plt.subplots` call above\r\n\r\n![image](https://user-images.githubusercontent.com/2448579/42615630-4d06edd2-8568-11e8-9486-ac79f07982c7.png)\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: Ubuntu 16.04\r\n  * Matplotlib version:  2.2.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): `module://ipykernel.pylab.backend_inline`\r\n  * Python version: 3.6.5\r\n  * Jupyter version (if applicable): 5.5.0\r\n  * Other libraries: \r\n\r\n\r\n","author":{"url":"https://github.com/dcherian","@type":"Person","name":"dcherian"},"datePublished":"2018-07-12T06:17:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/11641/matplotlib/issues/11641"}
