@markusritschel I tested v0.17.0 and it doesn't work.

data = np.random.rand(4, 3) locs = ["IA", "IL", "IN"] times = pd.date_range("2000-01-01", periods=4) foo = xr.DataArray(data, coords=[times, locs], dims=["time", "space"]) foo.groupby('space').argmax('time')

Error: AttributeError: 'DataArrayGroupBy' object has no attribute 'argmax'
