```
import xarray as xr
import numpy as np
import cartopy.crs as ccrs

da = xr.tutorial.open_dataset('air_temperature')['air']

p = da.isel(time=[0, 1]).plot(
    transform=ccrs.PlateCarree(), col='time',
    subplot_kws={'projection': ccrs.Orthographic(-80, 35)}
)

for ax in p.axes.flat:
    ax.coastlines()
    ax.gridlines()
```

```
p = da.isel(time=0).plot(
    transform=ccrs.PlateCarree(),
    subplot_kws={'projection': ccrs.Orthographic(-80, 35)}
)

However if you try iterating over the axes, it will crash because `p` is quadmesh type not a facetgrid type so I was wondering whether it'd be good to have an keyword like `force_facetgrid_type=True` which uses the FacetGrid class to plot a single map so that the user can keep the same code for single axes and facet axes?
```
p = da.isel(time=0).plot(
    transform=ccrs.PlateCarree(),
    subplot_kws={'projection': ccrs.Orthographic(-80, 35)}
)

for ax in p.axes.flat:
    ax.coastlines()
    ax.gridlines()
