Note that h1 is a list of length 1 of Line2D objects, while h2 is a PolarAxesSubplot object.\r\n\r\n### Expected outcome\r\n\r\nBoth points should be plotted.  Both h1 and h2 should be lists of length 1 of Line2D objects.\r\n\r\n### Operating system\r\n\r\nWindows\r\n\r\n### Matplotlib Version\r\n\r\n3.4.3\r\n\r\n### Matplotlib Backend\r\n\r\n_No response_\r\n\r\n### Python version\r\n\r\n3.9\r\n\r\n### Jupyter version\r\n\r\n_No response_\r\n\r\n### Other libraries\r\n\r\n_No response_\r\n\r\n### Installation\r\n\r\nconda\r\n\r\n### Conda channel\r\n\r\n_No response_","author":{"url":"https://github.com/beckja","@type":"Person","name":"beckja"},"datePublished":"2021-09-18T18:53:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/21113/matplotlib/issues/21113"}
