The `anchor` argument appears to be functionally ignored. (Note that `location` specifies left/right/top/bottom, whereas `anchor` should move the colorbar within the specified location, eg if the default location of right is chosen, anchor allows moving the colorbar to the top or bottom.)\r\n\r\nThis appears to be an incomplete implementation of the `constrained_layout.layoutcolorbargridspec` function, called from here:\r\n\r\nhttps://github.com/matplotlib/matplotlib/blob/c8b92926a880163394e3bd7f56220b65df71646c/lib/matplotlib/_constrained_layout.py\r\n\r\nPlease let me know if I'm missing something or if there's a workaround.\r\n\r\n**Code for reproduction**\r\n\r\n```python\r\nfig, ax = plt.subplots(constrained_layout=True)\r\nax.scatter(np.arange(100), np.arange(100), c=np.arange(100))\r\ncax, _ = matplotlib.colorbar.make_axes(ax, shrink=0.5, anchor=(0.0, 1.0))\r\ncbar = matplotlib.colorbar.ColorbarBase(cax)\r\n```\r\n\r\n**Actual outcome**\r\n\r\nWith `constrained_layout=True`:\r\n![image](https://user-images.githubusercontent.com/50211122/60208409-39f44600-9826-11e9-985c-090cc49a8393.png)\r\n\r\n**Expected outcome**\r\n\r\nWith `constrained_layout=True`, the anchor argument is honored:\r\n![image](https://user-images.githubusercontent.com/50211122/60208471-5b553200-9826-11e9-89e7-2b4bcf81493c.png)\r\n\r\n(Note that the colorbar has moved to the top, as expected given the `anchor=(0, 1.0)`.)\r\n\r\n","author":{"url":"https://github.com/nspies-celsiustx","@type":"Person","name":"nspies-celsiustx"},"datePublished":"2019-06-26T19:30:03.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/14638/matplotlib/issues/14638"}
