Chart Features




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.
