Dataset.unstack(dim=None, fill_value=<NA>, sparse=False)[source]#

Unstack existing dimensions corresponding to MultiIndexes into multiple new dimensions.

New dimensions will be added at the end.

  • dim (str, Iterable of Hashable or None, optional) – Dimension(s) over which to unstack. By default unstacks all MultiIndexes.

  • fill_value (scalar or dict-like, default: nan) – value to be filled. If a dict-like, maps variable names to fill values. If not provided or if the dict-like does not contain all variables, the dtype’s NA value will be used.

  • sparse (bool, default: False) – use sparse-array if True


unstacked (Dataset) – Dataset with unstacked data.
