What happened: I think the latest pandas (1.1.0) conflicts with faceting along time dimensions.

Minimal Complete Verifiable Example:

python import xarray as xr airtemps = xr.tutorial.open_dataset("air_temperature") airtemps['air'].isel(time=slice(2)).plot(col='time') This returns the following error: KeyError: 1356998400000000000
