We can either try to fix the problematic interaction between new-style colorbars and ImageGrid, or \"advantageously\" interpret the fact that no one reported this bug in the ~1.5y since the release of matplotlib 3.5 as a sign that ImageGrid sees very little use and perhaps deprecate it (it has a slightly idiosyncratic API anyways, and may be better replaced by compressed layout these days).\n\n### Operating system\n\nmacos\n\n### Matplotlib Version\n\n3.8.0.dev1020+gefd66d48fc\n\n### Matplotlib Backend\n\nmplcairo\n\n### Python version\n\n3.11\n\n### Jupyter version\n\nenosuchlib\n\n### Installation\n\ngit checkout","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2023-05-12T22:21:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/25876/matplotlib/issues/25876"}
