This is the inverse operation of Dataset.to_stacked_array.
- Parameters
- Returns
unstacked
- Return type
Examples
>>> arr = xr.DataArray( ... np.arange(6).reshape(2, 3), ... coords=[("x", ["a", "b"]), ("y", [0, 1, 2])], ... ) >>> data = xr.Dataset({"a": arr, "b": arr.isel(y=0)}) >>> data <xarray.Dataset> Dimensions: (x: 2, y: 3) Coordinates: * x (x) <U1 'a' 'b' * y (y) int64 0 1 2 Data variables: a (x, y) int64 0 1 2 3 4 5 b (x) int64 0 3 >>> stacked = data.to_stacked_array("z", ["x"]) >>> stacked.indexes["z"] MultiIndex([('a', 0.0), ('a', 1.0), ('a', 2.0), ('b', nan)], names=['variable', 'y']) >>> roundtripped = stacked.to_unstacked_dataset(dim="z") >>> data.identical(roundtripped) True
