The current version uses `pd.isnull` to remove invalid values from input data when making a colorbar. `pd.isnull([np.inf])` is False which means `_determine_cmap_params` returns Inf for colorbar limits which screws everything up. This PR changes `pd.isnull` to `np.isfinite`.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/2120/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
