I'm not sure this is the best behavior for this use case?\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\nfrom pylab import *\r\n\r\nax = gca()\r\nrs = ax.bar(np.arange(50), np.arange(50))\r\nax.bar_label(rs)\r\nax.set(ylim=(0, 40))\r\nshow()\r\n```\r\n\r\n**Actual outcome**\r\n\r\n![test](https://user-images.githubusercontent.com/1322974/106592644-1344d800-6550-11eb-8825-828e34b718ea.png)\r\n\r\nNote how the 39 and 40 labels are still drawn (effectively, because the bar tops are within axes limits), but not the subsequent ones.\r\n\r\n**Expected outcome**\r\n\r\nI'm not sure what the best behavior would be, but it should likely be one of the following:\r\n- perform \"normal\" clipping (so 39 is half-clipped, 40 is fully clipped out)\r\n- don't draw any labels that would be clipped (39 is hidden)\r\n- don't clip at all (all labels are visible)\r\n\r\nbar_label is new in 3.4 so it *may* be worth deciding on this before the 3.4 release.\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: linux\r\n  * Matplotlib version (`import matplotlib; print(matplotlib.__version__)`): head\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): agg\r\n  * Python version: 39\r\n  * Jupyter version (if applicable): \r\n  * Other libraries: \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(inspired by https://github.com/matplotlib/matplotlib/issues/19428, but that bug report is using a pre-bar_label labeling approach.)\r\n\r\n","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2021-02-02T11:16:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/19429/matplotlib/issues/19429"}
