JavaScript/jQuery RangeSelector API
The RangeSelector is a widget that allows a user to select a range of values on a scale.
This widget represents a scale (numeric or date-time) and two sliders. A user selects the required range by moving the sliders.
A chart can be displayed in the background of the RangeSelector widget. This allows end users to select the required range in a chart series. You can also integrate the RangeSelector widget with a stand-alone Chart widget to emulate chart zooming and scrolling.
