DevExtreme React - 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.

DevExtreme HTML5 JavaScript Charts LoadingIndicator

To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

JavaScript
  • $(function() {
  • $("#chartContainer").dxChart({
  • // ...
  • loadingIndicator: {
  • show: true
  • }
  • });
  • });

If you need to show or hide the loading indicator at runtime, call the showLoadingIndicator() or hideLoadingIndicator() method.

JavaScript
  • var chart = $("#chartContainer").dxChart("instance");
  • chart.showLoadingIndicator();
  • chart.hideLoadingIndicator();
