The axis CF property.

The axis property may be used to specify the type of coordinates. It may take one of the values 'X', 'Y', 'Z' or 'T' which stand for a longitude, latitude, vertical, or time axis respectively. A value of 'X', 'Y' or 'Z' may also also used to identify generic spatial coordinates (the values 'X' and 'Y' being used to identify horizontal coordinates).


>>> c.axis = 'Y'
>>> c.axis
>>> del c.axis
>>> c.set_property('axis', 'T')
>>> c.get_property('axis')
>>> c.del_property('axis')
