See https://github.com/matplotlib/matplotlib/pull/27780.\r\n\r\nThere is a `labels` parameter, but that only sets x-tick labels. And it has one entry per box. For the legend we should have only one entry per `boxplot()` call no matter how many boxes that has, because `boxplot` draws N identically styled boxes and it does not make sense to have N identical handles with different labels.\r\n\r\nBecause of the x-tick relation of  `labels` and it's relation to individual boxes, this parameter is not suited for the legend labels. \r\n\r\n### Proposed solution\r\n\r\nWe need a separate parameter. There are basically two options:\r\n\r\n#### Variant 1) `legend_label: str`\r\n\r\n*pro*: simple and clear, no interference with the existing API\r\n*con*: inconsistent with the rest of the library: all other functions use `label` for the legend entry.\r\n\r\n\r\n#### Variant 2) `label: str`\r\n*pro*: consistent with the rest of the library\r\n*con*: Having `label` alongside `labels` is quite confusing and easily leads to errors. (We could runtime-check for the type str vs list of str, to give helpful error messages but still ...)\r\nIf we want to go this way, we should rename `labels` to `tick_labels` or similar.\r\n","author":{"url":"https://github.com/timhoffm","@type":"Person","name":"timhoffm"},"datePublished":"2024-02-14T20:04:03.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/27792/matplotlib/issues/27792"}
