xarray.Index.stack

classmethod Index.stack(variables, dim)

Create a new index by stacking coordinate variables into a new dimension.

Implementation is optional but required in order to support stack. Otherwise it will raise an error when trying to pass the Index subclass as argument to Dataset.stack().

Parameters:

• variables (dict-like) – Mapping of Variable objects to stack together.

• dim (Hashable) – Name of the new, stacked dimension.

Returns:

index – A new Index object.
