248456545,MDU6SXNzdWUyNDg0NTY1NDU=,1504,cbar_kwargs for faceting plots,6894066,closed,0,,,0,2017-08-07T15:58:51Z,2018-10-25T16:06:53Z,2018-10-25T16:06:53Z,NONE,,,,"I'm using faceting and the add_colorbar=True argument along with cbar_kwargs. This triggers the following error message:

```
ValueError: cbar_ax and cbar_kwargs can't be used with add_colorbar=False.
```

I searched the facetgrid.py module and found the following lines:
```python
func_kwargs = kwargs.copy()
func_kwargs.update(cmap_params)
func_kwargs.update({'add_colorbar': False, 'add_labels': False})
```
I realized that if add_colorbar is True, then the facet function draws one colorbar for each subplot. My initial intention was providing cbar_kwargs to reduce the whitespace between the colorbar en the right edge of the plot.

Is there any way to fix this?","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/1504/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue
