RangeSelector Class

RangeSelector Class

The RangeSelector control displays a range selector that allows the user to choose the range of data to display on the specified FlexChart.

To use the RangeSelector control, specify the FlexChart control to display the selected range of data.

The rangeChanged event is fired when there is a change in min or max value. For example:

 var rangeSelector = new RangeSelector(chart);
 rangeSelector.rangeChanged.addHandler(function () {
    // perform related updates
    // e.g. modify displayed range of another chart
    update(rangeSelector.min, rangeSelector.max);
  });
