is specified, tick locations are adjusted according
values for Graduation.VISUAL_AXIS_LENGTH

- Rendering hints, or null
for the default hints.reuse
- An iterator to reuse if possible, or null
to create a new one. A non-null object may help to reduce the
number of object garbage-collected when rendering the axis.
