pcolormesh expects n+1 coordinates

I agree that pcolormesh ultimately works with the mesh corners, but I am pretty sure passing coordinates of the same length also works.

you'll probably have to sort the values beforehand too

True. But we can do it automatically with xarray because it has the coordinate information.

So the question is how much sanity check xarray should do before sending the data to matplotlib, and maybe a warning of some kind would be useful.

I am not sure there there is any circumstance where it would be preferable to plot the scrambled data. Is there some the problem with just adding something like the two lines a wrote above to plot.pcolormesh?
