Discrete Aggregation

The aggregation algorithm depends on the aggregateByCategory option. In this demo, this option is set to true and applies the "sum" aggregation method for the groups specified in the dataSource.

If aggregateByCategory is false, the specified aggregation method is not applied. The first series point is displayed instead.
