It doesn’t cycle automatically. Is this behavior expected? Do I need to manually setup the color cycling? If so how can I do this easily? Why does matplotlib not automatically cycle through the colors for `axhline`?\r\n\r\nmatplotlib v3.2.0\r\n\r\n```\r\n%matplotlib widget\r\nimport matplotlib.pyplot as plt\r\n\r\nfig, ax = plt.subplots()\r\n\r\ncount = 5\r\n\r\nfor n in range(count):\r\n    ax.axhline(y=n**2, label=n) \r\n    \r\nax.legend()\r\nplt.show()\r\n```\r\n![image](https://user-images.githubusercontent.com/43527304/76243175-4b437e00-620e-11ea-8258-8a49d15bf2bf.png)\r\n","author":{"url":"https://github.com/01baftb","@type":"Person","name":"01baftb"},"datePublished":"2020-03-09T18:02:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":19},"url":"https://github.com/16714/matplotlib/issues/16714"}
