I decided to open a separate issue because there's a lot going on in the original thread.\r\n\r\n(BTW I do support the suggestion in the original thread that `get_{x/y}ticklabels` should implicitly draw so that it always returns a sensible result).\r\n\r\n**Code for reproduction**\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nax = plt.figure().subplots()\r\nax.plot([\"a\", \"b\", \"c\"], [1, 2, 3])\r\nax.figure.canvas.draw()\r\nprint(ax.get_xticklabels())\r\n```\r\n\r\n**Actual outcome**\r\n\r\n\u003c!--The output produced by the above code, which may be a screenshot, console output, etc.--\u003e\r\n\r\nUsing the MacOSX backend:\r\n\r\n```\r\n[Text(0, 0, ''), Text(0, 0, ''), Text(0, 0, '')]\r\n```\r\n\r\n**Expected outcome**\r\n\r\nUsing an agg-based backend:\r\n\r\n```\r\n[Text(0, 0, 'a'), Text(1, 0, 'b'), Text(2, 0, 'c')]\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:\r\n  * Matplotlib version: (`import matplotlib; print(matplotlib.__version__)`) 3.3.3\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): macosx\r\n  * Python version: 3.8\r\n  * Jupyter version (if applicable): n/a\r\n  * Other libraries: n/a\r\n","author":{"url":"https://github.com/mwaskom","@type":"Person","name":"mwaskom"},"datePublished":"2021-01-09T13:20:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/19268/matplotlib/issues/19268"}
