Found a solution for 1. This function works really well even when resizing a figure on matplotlib 3.0.2:

``` python def make_colorbar(ax, mappable, **kwargs): from mpl_toolkits.axes_grid1 import make_axes_locatable import matplotlib as mpl

divider = make_axes_locatable(ax)
orientation = kwargs.pop('orientation', 'vertical')
if orientation == 'vertical':
    loc = 'right'
elif orientation == 'horizontal':
    loc = 'bottom'

cax = divider.append_axes(loc, '5%', pad='3%', axes_class=mpl.pyplot.Axes)
ax.get_figure().colorbar(mappable, cax=cax, orientation=orientation)

```

```python import cartopy.crs as ccrs import xarray as xr

ds = xr.tutorial.open_dataset('air_temperature').load()

ax = plt.subplot(projection=ccrs.LambertConformal()) mappable = ds.air.isel(time=0).plot(transform=ccrs.PlateCarree(), add_colorbar=False) ax.coastlines() ax.gridlines()

make_colorbar(ax, mappable, orientation='vertical') ```

``` python ds = xr.tutorial.open_dataset('air_temperature').load()

ax = plt.subplot(projection=ccrs.LambertConformal()) mappable = ds.air.isel(time=0).plot(transform=ccrs.PlateCarree(), add_colorbar=False) ax.coastlines() ax.gridlines()

make_colorbar(ax, mappable, orientation='horizontal') ```
