xarray.Coordinates

class xarray.Coordinates(coords=None, indexes=None)

Dictionary like container for Xarray coordinates (variables + indexes).

This collection is a mapping of coordinate names to DataArray objects.

It can be passed directly to the Dataset and DataArray constructors via their coords argument. This will add both the coordinates variables and their index.

Coordinates are either:

• returned via the Dataset.coords and DataArray.coords properties.

• built from index objects (e.g., Coordinates.from_pandas_multiindex()).

• built directly from coordinate data and index objects (beware that no consistency check is done on those inputs).

In the latter case, no default (pandas) index is created.

Parameters:

• coords (dict-like) – Mapping where keys are coordinate names and values are objects that can be converted into a Variable object (see as_variable()).

• indexes (dict-like) – Mapping of where keys are coordinate names and values are Index objects.

__init__(coords=None, indexes=None)

Methods

__init__([coords, indexes])
copy([deep, memo])	Return a copy of this Coordinates object.
equals(other)	Two Coordinates objects are equal if they have matching variables, all of which are equal.
from_pandas_multiindex(midx, dim)	Wrap a pandas multi-index as Xarray coordinates (dimension + levels).
get(k[,d])
identical(other)	Like equals, but also checks all variable attributes.
items()
keys()
merge(other)	Merge two sets of coordinates to create a new Dataset
to_dataset()	Convert these coordinates into a new Dataset.
to_index([ordered_dims])	Convert all index coordinates into a pandas.Index.
update(other)	Update this Coordinates variables with other coordinate variables.
values()

Attributes

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