JavaScript/jQuery Chart - Loading Indicator
When the Chart visualizes local data, loading is instant. But when the Chart is bound to a remote data source, loading may take a considerable amount of time. To keep the viewer's attention, the Chart can display a loading indicator.
To activate the loading indicator, assign true to the loadingIndicator.enabled property. When activated, the indicator will be displayed or hidden automatically as the chart's data is updated.
- $(function() {
- $("#chartContainer").dxChart({
- // ...
- loadingIndicator: {
- enabled: true
- }
- });
- });
If you need to show or hide the loading indicator at runtime, call the showLoadingIndicator() or hideLoadingIndicator() method.
- var chart = $("#chartContainer").dxChart("instance");
- chart.showLoadingIndicator();
- chart.hideLoadingIndicator();
