Vue RangeSelector API

The RangeSelector is a widget that allows a user to select a range of values on a scale.

import DxRangeSelector from "devextreme-vue/range-selector"

This widget represents a scale (numeric or date-time) and two sliders. A user selects the required range by moving the sliders.

RangeSelector

DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.

The following code shows how to create the RangeSelector widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.

    .ID("rangeSelector") _
    .Scale(Sub(scale)
        scale.StartValue(New DateTime(2011, 1, 1)) _

                .TickInterval(Sub(ti) ti.Days(7))
    End Sub)
)

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.
