In 3.1.0, and in 3.1.1 when not calling `set_yticks`, the plot includes the outer 0.5 bin in the top and bottom rows. This is the desired behavior. But in 3.1.1 when using `set_yticks`, the outer 0.5 bin in the top and bottom rows is not included in the plot. \r\n\r\n**Code for reproduction**\r\n```python\r\nimport matplotlib\r\nimport matplotlib.pyplot as plt\r\n\r\nxy = [[1, 3], [2, 4]]\r\nfig, ax = matplotlib.pyplot.subplots(1)\r\nax.imshow(xy)\r\nax.set_xticks([0, 1])\r\nax.set_xticklabels([\"0\", \"1\"])\r\nax.set_yticks([0, 1])\r\nax.set_yticklabels([\"0\", \"1\"])\r\nfig.savefig(f\"matplotlib-v{matplotlib.__version__}.png\")\r\n```\r\nThe behavior changes in 3.1.1 if `ax.set_yticks([0, 1])` is commented out.\r\n\r\nDesired behavior\r\n![image](https://user-images.githubusercontent.com/6991781/61991111-66a3a500-b000-11e9-9ad2-04613b8a1a81.png)\r\n\r\nBehavior in 3.1.1 with `set_yticks`\r\n![image](https://user-images.githubusercontent.com/6991781/61991098-4aa00380-b000-11e9-84b4-303fde60972c.png)\r\n\r\n**Matplotlib version**\r\n  * Operating system: Mac OS 10.14.5\r\n  * Matplotlib version: 3.1.1\r\n  * Matplotlib backend: agg\r\n  * Python version: 3.7.3\r\n  * Jupyter version (if applicable): N/A\r\n  * Other libraries: Fresh conda install of just matplotlib, using conda-forge","author":{"url":"https://github.com/caldwellshane","@type":"Person","name":"caldwellshane"},"datePublished":"2019-07-27T06:57:53.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/14897/matplotlib/issues/14897"}
