cf.Field.cyclic¶

Field.
cyclic
(*identity, iscyclic=True, period=None, config={}, **filter_kwargs)[source]¶ Set the cyclicity of an axis.
New in version 1.0.

 Parameters
 identity, filter_kwargs: optional
Select the unique domain axis construct returned by
f.domain_axis(*identity, **filter_kwargs)
. Seedomain_axis
for details. iscyclic:
bool
, optional If False then the axis is set to be noncyclic. By default the selected axis is set to be cyclic.
 period: optional
The period for a dimension coordinate construct which spans the selected axis. May be any numeric scalar object that can be converted to a
Data
object (which includes numpy array andData
objects). The absolute value of period is used. If period has units then they must be compatible with those of the dimension coordinates, otherwise it is assumed to have the same units as the dimension coordinates. config:
dict
, optional Additional parameters for optimising the operation. See the code for details.
New in version 3.9.0.
 axes: deprecated at version 3.0.0
Use the identity and filter_kwargs parameters instead.
 Returns
set
The construct keys of the domain axes which were cyclic prior to the new setting, or the current cyclic domain axes if no axis was specified.
Examples
>>> f.cyclic() set() >>> f.cyclic('X', period=360) set() >>> f.cyclic() {'domainaxis2'} >>> f.cyclic('X', iscyclic=False) {'domainaxis2'} >>> f.cyclic() set()
