Here is a test script to reproduce the issue:\r\n\r\n```python\r\n# Python 3.6\r\nimport matplotlib.pyplot as plt\r\nimport matplotlib\r\nimport numpy as np\r\nrng = np.random.RandomState(829)\r\n\r\nt = np.concatenate([rng.randn(100),\r\n                    2 + 0.1 * rng.randn(100),\r\n                    5 + 3 * rng.randn(100)])\r\nplt.hist(t, bins=[-5, -3, -2, -1, -0.5, 0, 2, 4, 5, 10], normed=True)\r\nplt.title(f'matplotlib v{matplotlib.__version__}')\r\nplt.savefig(f'hist-{matplotlib.__version__}.png')\r\nplt.show()\r\n```\r\n\r\n``hist-2.0.2.png``:\r\n![hist-2 0 2](https://user-images.githubusercontent.com/781659/31950156-d6df03a6-b88f-11e7-80f7-f43c54ce958c.png)\r\n\r\n``hist-2.1.0.png``:\r\n![hist-2 1 0](https://user-images.githubusercontent.com/781659/31950167-d9952de6-b88f-11e7-87a7-6161438df17a.png)\r\n\r\n\r\n\r\n\r\n","author":{"url":"https://github.com/jakevdp","@type":"Person","name":"jakevdp"},"datePublished":"2017-10-24T14:52:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":28},"url":"https://github.com/9557/matplotlib/issues/9557"}
