Drop coordinates or index labels from this DataArray.

        Parameters
        ----------
        labels : scalar or list of scalars
            Name(s) of coordinate variables or index labels to drop.
        dim : str, optional
            Dimension along which to drop index labels. By default (if
            ``dim is None``), drops coordinates rather than index labels.

        Returns
        -------
        dropped : DataArray
