The Chart component can aggregate series points. To enable this feature, set the aggregation.enabled property of a series to true.
In this demo, the Chart is bound to the RangeSelector component. If you set the selection to a wide range, the control will use a higher aggregation degree, and vice versa.
Aggregation on zoom is one of many possible use cases for this feature. For information on how to configure aggregation for other scenarios, refer to the following description: aggregation.
