Coordinates

Creating coordinates

Coordinates([coords, indexes])	Dictionary like container for Xarray coordinates (variables + indexes).
Coordinates.from_xindex(index)	Create Xarray coordinates from an existing Xarray index.
Coordinates.from_pandas_multiindex(midx, dim)	Wrap a pandas multi-index as Xarray coordinates (dimension + levels).

Attributes

Coordinates.dims	Mapping from dimension names to lengths or tuple of dimension names.
Coordinates.sizes	Mapping from dimension names to lengths.
Coordinates.dtypes	Mapping from coordinate names to dtypes.
Coordinates.variables	Low level interface to Coordinates contents as dict of Variable objects.
Coordinates.indexes	Mapping of pandas.Index objects used for label based indexing.
Coordinates.xindexes	Mapping of Index objects used for label based indexing.

Dictionary Interface

Coordinates implement the mapping interface with keys given by variable names and values given by DataArray objects.

Coordinates.__getitem__(key)
Coordinates.__setitem__(key, value)
Coordinates.__delitem__(key)
Coordinates.update(other)	Update this Coordinates variables with other coordinate variables.
Coordinates.get(k[,d])
Coordinates.items()
Coordinates.keys()
Coordinates.values()

Coordinates contents

Coordinates.to_dataset()	Convert these coordinates into a new Dataset.
Coordinates.to_index([ordered_dims])	Convert all index coordinates into a pandas.Index.
Coordinates.assign([coords])	Assign new coordinates (and indexes) to a Coordinates object, returning a new object with all the original coordinates in addition to the new ones.
Coordinates.merge(other)	Merge two sets of coordinates to create a new Dataset
Coordinates.copy([deep, memo])	Return a copy of this Coordinates object.

Comparisons

Coordinates.equals(other)	Two Coordinates objects are equal if they have matching variables, all of which are equal.
Coordinates.identical(other)	Like equals, but also checks all variable attributes.

Proxies

Coordinates that are accessed from the coords property of Dataset, DataArray and DataTree objects, respectively.

DatasetCoordinates(dataset)	Dictionary like container for Dataset coordinates (variables + indexes).
DataArrayCoordinates(dataarray)	Dictionary like container for DataArray coordinates (variables + indexes).
DataTreeCoordinates(datatree)	Dictionary like container for coordinates of a DataTree node (variables + indexes).
