But the main idea is probably still useful.\r\n\r\n#11127 is a bit different, it would create many legend entries for a single scatterplot. The idea here was to unify the size of different scatter plot's handles. Many options are shown in [the stackoverflow question \"setting a fixed size for points in legend\"](https://stackoverflow.com/questions/24706125/setting-a-fixed-size-for-points-in-legend). The easiest is just:\r\n\r\n```\r\nlegend = plt.legend()\r\nfor legobj in legend.legendHandles:\r\n    legobj.set_sizes([64])\r\n```\r\n\r\nMy faviourite, which I just added to that thread as well would be to use the update function of the Handler.\r\n\r\n```\r\ndef update(handle, orig):\r\n    handle.update_from(orig)\r\n    handle.set_sizes([64])\r\n\r\nplt.legend(handler_map={PathCollection : HandlerPathCollection(update_func=update)})\r\n```\r\n\r\n_Originally posted by @ImportanceOfBeingErnest in https://github.com/matplotlib/matplotlib/pull/4257#issuecomment-427536275_","author":{"url":"https://github.com/jklymak","@type":"Person","name":"jklymak"},"datePublished":"2018-10-06T02:01:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/12417/matplotlib/issues/12417"}
