DxChartStepLineSeries<T, TArgument, TValue> Class

Defines a step line series.

Assembly : DevExpress.Blazor.v25.2.dll

Declaration

csharp

public class DxChartStepLineSeries<T, TArgument, TValue> :
    DxChartLineSeriesBase<T, TArgument, TValue>

Type Parameters

Name	Description
T

The data type.

| | TArgument |

The argument type.

| | TValue |

The value type.

Remarks

Step line series display data as points joined by horizontal and vertical line segments that form a step-like pattern. Follow the steps below to create a step line series:

Use the DxChart.Data property to specify a data source.
Add a DxChartStepLineSeries object to chart markup.
Use series ArgumentField and ValueField properties to specify data source fields that supply arguments and values for chart points.
Optional. Specify series Filter and SummaryMethod properties to filter and aggregate series values.

The following example filters data by region. It also groups arguments by date and calculates aggregate values using the Enumerable.Sum method. For a sample data source, refer to our GitHub repository.
