cf.Field.cyclic¶

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

 Parameters
 identity:
Select the domain axis construct by one of:
An identity or key of a 1d coordinate construct that whose data spans the domain axis construct.
A domain axis construct identity or key.
The position of the domain axis construct in the field construct’s data.
The identity parameter selects the domain axis as returned by this call of the field construct’s
domain_axis
method:f.domain_axis(identity)
. 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. axes: deprecated at version 3.0.0
Use the identity parameter instead.
kwargs: deprecated at version 3.0.0
 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()
