xarray.DataArray.cf.axes¶
- DataArray.cf.axes¶
Mapping valid Axis standard names for
.cf[]
to variable names.This is useful for checking whether a key is valid for indexing, i.e. that the attributes necessary to allow indexing by that key exist. However, it will only return the Axis names
("X", "Y", "Z", "T")
present in.coords
, not in.data_vars
.- Returns:
- dict
Dictionary with keys that can be used with
__getitem__
or as.cf[key]
. Keys will be the appropriate subset of (“X”, “Y”, “Z”, “T”). Values are lists of variable names that match that particular key.
