DxChartStepAreaSeries<T, TArgument, TValue> Class

Defines a step area series.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v20.2.dll

Declaration

public class DxChartStepAreaSeries<T, TArgument, TValue> :
    DxChartSeries<T, TArgument, TValue, ChartStepAreaSeriesModel<T, TArgument, TValue>>

Type Parameters

Name Description
T

The type of data.

TArgument

The type of series arguments.

TValue

Remarks

The step area series displays data as a polyline that connects the series values by horizontal and vertical line segments. The area between the polyline and the argument axis is shaded with a color.

Use the chart's Data property to specify an IEnumerable<T> data source, and the 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.
