| Parameters: |
- axis, kwargs : optional
Select the unique axis which would be selected by this call of
the field’s axes method: f.axes(axis, **kwargs). See
cf.Field.axes for details.
- value : data-like
Anchor the dimension coordinate values for the selected cyclic
axis to this value. The coordinate values are transformed so
that value is “equal to or just before” the new first
coordinate value. More specifically:
- Increasing dimension coordinates with positive period, P,
are transformed so that value lies in the half-open
range (L-P, F], where F and L are the new first and last
coordinate values, respectively.
- Decreasing dimension coordinates with positive period, P,
are transformed so that value lies in the half-open
range (L+P, F], where F and L are the new first and last
coordinate values, respectively.
- i : bool, optional
If True then update the field in place. By default a new field
is created.
- _dry_run : bool, optional
Return a dictionary of parameters which describe the anchoring
process. The field is not changed, even if i is True.
