The right thing for xarray to do is probably to throw an error when any 2d plot method is called with 2 coordinates that actually have higher dimensions.

I disagree. I don't want to use the default dimensions as the x and y coords for the plot. I want to use the true lat / lon coords, which are xc and yc. In this case, I think the plot broke because pcolormesh can't handle the way the coordinates wrap. It's not a problem with xarray. If I pass the plot through cartopy, it actually works great, because cartopy knows how to handle the 2D geographic coordinates a bit better.

python ax = plt.axes(projection=ccrs.PlateCarree()) ax.set_global() ds.Tair[0].plot.pcolormesh(ax=ax, transform=ccrs.PlateCarree(), x='xc', y='yc') ax.coastlines()

This would fail of course if you could only use 1d coords for plotting, so I definitely think we should keep the plot code as is for now (not raise an error).

I am happy with this example for now.
