I've used the [gallery](http://xarray.pydata.org/en/latest/auto_gallery/plot_cartopy_facetgrid.html#sphx-glr-auto-gallery-plot-cartopy-facetgrid-py) to document these kind of things. It's a bit lost in the doc currently though.

Looks like we need it for these kind of feature, right?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,362918990

The equivalent for facetgrid is 
```
g = air.isel(time=slice(0, 2)).plot.contour(col='time', colors='k')
for cs, ax in zip(g._mappables, g.axes.flat):
    ax.clabel(cs)
```

So adding this would make that a little more convenient. If not, I can send in a PR to document this bit (the use of `_mappables` is not very obvious; maybe we should make it public?)

It looks like it's only saves a few characters over just calling `ax.clabel()` afterwards.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,362918990
