You can enable the axis zooming with 'zoomEnabled' axis option. When the zooming
is enabled a range selector is displayed along the axis.
With visibleMinimum and visibleMaximum options you can specify the beginning and
the end of the visible range.
For detailed implementation, please take a look at the HTML code tab.
