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.
To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.
If you need to show or hide the loading indicator at runtime, call the showLoadingIndicator() or hideLoadingIndicator() method.
