larray.Axis.extend¶

Axis.extend(self, labels)[source]¶

Append new labels to an axis or increase its length in case of wildcard axis. Note that extend does not occur in-place: a new axis object is allocated, filled and returned.

Parameters

labelsint, iterable or Axis: New labels to append to the axis. Passing directly another Axis is also possible. If the current axis is a wildcard axis, passing a length is enough.

Returns

Axis: A copy of the axis with new labels appended to it or with increased length (if wildcard).

Examples

>>> time = Axis([2007, 2008], 'time')
>>> time
Axis([2007, 2008], 'time')
>>> time.extend([2009, 2010])
Axis([2007, 2008, 2009, 2010], 'time')
>>> waxis = Axis(10, 'wildcard_axis')
>>> waxis
Axis(10, 'wildcard_axis')
>>> waxis.extend(5)
Axis(15, 'wildcard_axis')
>>> waxis.extend([11, 12, 13, 14])

ValueError: Axis to append must (not) be wildcard if self is (not) wildcard
