        Only the data is moved; coordinates stay in place. This is consistent
        with the behavior of ``shift`` in pandas.

        Values shifted from beyond array bounds will appear at one end of
        each dimension, which are filled according to `fill_value`. For periodic
        offsets instead see `roll`.

        Parameters
        ----------
        shifts : mapping of Hashable to int or None, optional
            Integer offset to shift along each of the given dimensions.
            Positive offsets shift to the right; negative offsets shift to the
            left.
        fill_value : scalar, optional
            Value to use for newly missing values
        **shifts_kwargs
            The keyword arguments form of ``shifts``.
            One of shifts or shifts_kwargs must be provided.

        Returns
        -------
        shifted : DataArray
            DataArray with the same coordinates and attributes but shifted
            data.

        --------

        --------
        >>> arr = xr.DataArray([5, 6, 7], dims="x")
        >>> arr.shift(x=1)
        <xarray.DataArray (x: 3)> Size: 24B
