xarray.Dataset.unstack (original) (raw)

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

Unstack existing dimensions corresponding to MultiIndexes into multiple new dimensions.

New dimensions will be added at the end.

Parameters:

• 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

Returns:

unstacked (Dataset) – Dataset with unstacked data.
