RangeSelector

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

Included in: dx.viz.js, dx.viz-web.js, dx.all.js

Module: viz/range_selector

Export: default

$("#rangeselector").dxRangeSelector({

});

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

RangeSelector

You can create the widget using one of the following approaches.

jQuery

HTML

JavaScript

<div id="rangeSelector"></div>

$(function() {
    $("#rangeSelector").dxRangeSelector({
        scale: {
            startValue: new Date(2011, 0, 1),
            endValue: new Date(2011, 5, 1),
            tickInterval: { days: 7 }
        }
    });
});

Angular

HTML

JavaScript

<dx-range-selector>
    <dxo-scale
        [startValue]="startDate"
        [endValue]="endDate">
        <dxo-tick-interval [days]="7"></dxo-tick-interval>
    </dxo-scale>
</dx-range-selector>

export class AppComponent {
    startDate = new Date(2011, 0, 1);
    endDate = new Date(2011, 5, 1);
}

AngularJS

HTML

JavaScript

<div ng-controller="DemoController">
    <div dx-range-selector="{
        scale: {
            startValue: startDate,
            endValue: endDate,
            tickInterval: { days: 7 }
        }
    }"></div>
</div>

angular.module('DemoApp', ['dx'])
    .controller("DemoController", function ($scope) {
        $scope.startDate = new Date(2011, 0, 1);
        $scope.endDate = new Date(2011, 5, 1);
    });

Knockout

HTML

<div data-bind="dxRangeSelector: {
    scale: {
        startValue: new Date(2011, 0, 1),
        endValue: new Date(2011, 5, 1),
        tickInterval: { days: 7 }
    }
}"></div>

ASP.NET MVC Wrappers

Razor C#

Razor VB

@(Html.DevExtreme().RangeSelector()
    .ID("rangeSelector")
    .Scale(scale => scale
        .StartValue(new DateTime(2011, 1, 1))
        .EndValue(new DateTime(2011, 6, 1))
        .TickInterval(ti => ti.Days(7))
    )
)

@(Html.DevExtreme().RangeSelector() _
    .ID("rangeSelector") _
    .Scale(Sub(scale)
        scale.StartValue(New DateTime(2011, 1, 1)) _
             .EndValue(New DateTime(2011, 6, 1)) _
             .TickInterval(Sub(ti) ti.Days(7))
    End Sub)
)

Note that DevExtreme widgets require you to link the jQuery library to your application. If you use the Knockout or AngularJS approach, the Knockout or AngularJS library is also required. For detailed information on linking these libraries to your project, refer to the topics in the Installation section.

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.
