Hi,
i was giving a spin to the plot functionality, tinkering with @rabernat 's code (xarray_multidimensional_coords.ipynb).

That notebook works flawlessly with my setup (Mac OS 10.12.4, Python 3.5, cartopy 0.1.5, numpy 1.11.3, pandas version : 0.19.2, xarray version : 0.9.1), but if I change the projection from PlateCarree() to Robinson(), the map never shows up. What am I doing wrong?
