https://github.com/pyviz/hvplot/issues/244) where hvplot does *not* do the
right thing. But matplotlib (and hence also xarray.plot) do the right thing.

I think this is probably easy to fix by using `xr.broadcast` to broadcast things before extracting the numpy arrays. Can you send in a PR?

I *think* should be relatively straightforward to fix, assuming that the underlying maptlotlib plotting functions handle 2D coordinates.

For reference, here's the full error traceback:
