DxChartAreaSeries<T, TArgument, TValue> Class

Defines an area series.

Assembly: DevExpress.Blazor.v25.2.dll

Declaration

public class DxChartAreaSeries<T, TArgument, TValue> :
    DxChartAreaSeriesBase<T, TArgument, TValue>

Type Parameters

Name	Description
T	The data type.
TArgument	The argument type.
TValue	The value type.

Remarks

The area series displays data as a polyline that connects the series values. The area between the polyline and the argument axis is shaded with a color.

Follow the steps below to create an area series:

Use the DxChart.Data property to specify an IEnumerable<T> data source.
Add a DxChartAreaSeries object to chart markup.
Use series ArgumentField and ValueField properties to specify data source fields that contain arguments and values for chart points.

For a sample data source, refer to our GitHub repository.
