I'm trying to plot a dataset that has variable coordinates, and am getting behavior that is unexpected, and I wonder if it is a design issue or a user issue (i.e. I don't grok xarray). I've posted the question on SO (https://stackoverflow.com/questions/45474153/plotting-xarray-datasets-with-variable-coordinates).

Is the behavior that xarray is showing by design or is it a corner case that I'm getting because I'm not using xarray in the way it was originally intended?
