Could then probably adapt [scatter.legend_elements](https://matplotlib.org/devdocs/gallery/lines_bars_and_markers/scatter_with_legend.html#automated-legend-creation) implementation to auto generate legends from the colors. \r\n\r\nETA: If we did this, it'd probably also be a good reason to implement #7383 ","author":{"url":"https://github.com/story645","@type":"Person","name":"story645"},"datePublished":"2023-07-14T21:08:39.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/26312/matplotlib/issues/26312"}
