JavaScript/jQuery Range Selector - Date-Time Scale

In this demo, data used to define the JavaScript RangeSelector scale comes in the string type. However, there is the valueType property that specifies the actual scale data type. As this property is set to «datetime», the string data will be cast to the date type.

Backend API
$(() => { $('#range-selector').dxRangeSelector({ dataSource, margin: { top: 50, }, chart: { commonSeriesSettings: { type: 'steparea', argumentField: 'date', }, series: [ { valueField: 'dayT', color: 'yellow' }, { valueField: 'nightT' }, ], }, scale: { minorTickInterval: 'day', tickInterval: { days: 2 }, valueType: 'datetime', }, sliderMarker: { format: 'day', }, value: ['2013/03/01', '2013/03/07'], title: 'Select a Month Period', }); });
