Fires when the minimum and maximum is set for the axis, either by
calling the .setExtremes() method or by selecting an area in the
chart. One parameter, event, is passed to the function,
containing common event information.
The new user set minimum and maximum values can be found by
event.min and event.max. These reflect the axis minimum and
maximum in data values. When an axis is zoomed all the way out from
the "Reset zoom" button, event.min and event.max are null, and
the new extremes are set based on this.dataMin and this.dataMax.
