DxChartStackedSplineAreaSeries<T, TArgument, TValue> Class

Defines a stacked spline area series.

Assembly : DevExpress.Blazor.v25.2.dll

Declaration

csharp

public class DxChartStackedSplineAreaSeries<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 stacked spline area series displays data as a spline interpolation of the series values. The area between the spline and the argument axis (or a lower series) is shaded with a color. Different series do not overlap because their values are stacked.

Follow the steps below to create a stacked spline area series:

Use the DxChart.Data property to specify an IEnumerable<T> data source.
Add a DxChartStackedSplineAreaSeries 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.
