Discrete Aggregation

To aggregate points on discrete axes, follow the steps below:

  1. Enable aggregation.
    You can enable data aggregation for the following series:

Individual series aggregation settings have priority over common aggregation settings in the component. For example, you can enable aggregation for all series and disable it for a specific series.

In this demo, data aggregation is enabled for all series.

  1. Specify an aggregation method (optional).
    In this demo, the sum method is used.
