The expectation is that annotations would overlap the subplots.  \r\n\r\nLooking at the documentation...\r\n\r\nhttps://matplotlib.org/3.2.2/tutorials/intermediate/tight_layout_guide.html#caveats\r\n\r\n\u003e tight_layout() only considers ticklabels, axis labels, and titles. Thus, other artists may be clipped and also may overlap\r\n\r\nWith that in mind,  `tight_layout` should not consider `Text` annotations, and shouldn't adjust the subplot size when added.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug.\r\nPlease make sure to minimize the number of dependencies required, and provide\r\nany necessary plotted data.\r\nAvoid using threads, as Matplotlib is (explicitly) not thread-safe.--\u003e\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\n\r\nx = np.linspace(0,np.pi*2,1000)\r\ny = np.sin(x)\r\ndy = np.cos(x)\r\ndy2 = -np.sin(x)\r\n\r\nfor b in [False,True]:\r\n\r\n    h, ax = plt.subplots(3,1,sharex = True)\r\n    h.set_tight_layout(b)\r\n    ax[0].plot(x,y)\r\n    ax[1].plot(x,dy)\r\n    ax[2].plot(x,dy2)\r\n\r\n    ax[2].annotate(s = f'Annotation When Tight Layout is {b}', xy = (np.pi,-1), rotation = 'vertical')\r\n```\r\n\r\n**Actual outcome**\r\n\r\n![image](https://user-images.githubusercontent.com/20617349/88705768-9a168500-d0d5-11ea-969c-dbcaec24ac8d.png)\r\n\r\n**Expected outcome**\r\n\r\nIn this case,  `tight_layout` is set to FALSE just to see visually what it looks like with the text overlayed\r\n\r\n![image](https://user-images.githubusercontent.com/20617349/88705827-aac6fb00-d0d5-11ea-84d4-25c0e3214b18.png)\r\n\r\n\u003c!--A description of the expected outcome from the code snippet--\u003e\r\n\u003c!--If this used to work in an earlier version of Matplotlib, please note the version it used to work on--\u003e\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: CentOS Linux 7 (Core)\r\n  * Matplotlib version:  3.2.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): Qt5Agg\r\n  * Python version: 3.8.3\r\n  * Jupyter version (if applicable):\r\n  * Other libraries: numpy 1.18.5\r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\r\n\r\nconda\r\n\r\n\u003c!--If you installed from conda, please specify which channel you used if not the default--\u003e\r\n\r\nconda-forge","author":{"url":"https://github.com/Aerovet","@type":"Person","name":"Aerovet"},"datePublished":"2020-07-28T18:44:36.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/18098/matplotlib/issues/18098"}
