Update Circular Gauge Data at Runtime

Documentation

This demo illustrates how to bind an array of subvalues to the CircularGauge. Since an array can not be bound to a field as a regular value, it is bound as a computed one.

Backend API
$(() => { const gauge = $('#gauge').dxCircularGauge({ scale: { startValue: 10, endValue: 40, tickInterval: 5, label: { customizeText(arg) { return `${arg.valueText} °C`; }, }, }, rangeContainer: { ranges: [ { startValue: 10, endValue: 20, color: '#0077BE' }, { startValue: 20, endValue: 30, color: '#E6E200' }, { startValue: 30, endValue: 40, color: '#77DD77' }, ], }, tooltip: { enabled: true }, title: { text: 'Temperature in the Greenhouse', font: { size: 28 }, }, value: dataSource[0].mean, subvalues: [dataSource[0].min, dataSource[0].max], }).dxCircularGauge('instance'); $('#seasons').dxSelectBox({ width: 150, dataSource, inputAttr: { 'aria-label': 'Season' }, displayExpr: 'name', value: dataSource[0], onSelectionChanged(e) { gauge.option('value', e.selectedItem.mean); gauge.option('subvalues', [e.selectedItem.min, e.selectedItem.max]); }, }); });
