The DevExpress Chart component for Blazor supports real-time data updates. If data changes, the component only re-renders affected data points and retains its visual state (zoom and scroll position). You can use the VisualRangeUpdateMode property to change the update mode of the visual range.

If the Chart contains a large number of points, you can aggregate data to optimize performance. To enable this functionality, complete the following steps:

1. Add a DxChartAggregationSettings object to chart markup.
2. Set the DxChartAggregationSettings.Enabled property to true.
3. Specify an aggregation method in the DxChartAggregationSettings.Method property.
