PolarChartArgumentAxisBuilder.ConstantLines(Action<CollectionFactory<PolarChartArgumentAxisConstantLineBuilder>>) Method

Provides access to the client-side constantLines option that represents a constant line collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public PolarChartArgumentAxisBuilder ConstantLines(
    Action<CollectionFactory<PolarChartArgumentAxisConstantLineBuilder>> configurator
)

Parameters

Name	Type	Description
configurator	Action<CollectionFactory<PolarChartArgumentAxisConstantLineBuilder>>	A function that allows you to add items to the collection.

Returns

Type	Description
PolarChartArgumentAxisBuilder	A reference to this instance after the method is called.

Remarks

To configure a constant line collection, use a multiline lambda expression. In this case, a lambda parameter performs the role of a collection factory, and its Add() method adds a new item to the collection. The Add() method returns PolarChartArgumentAxisConstantLineBuilder whose methods you can use to configure an item.

Razor C#

@(Html.DevExtreme().PolarChart()
    .ArgumentAxis(axis => axis
        .ConstantLines(constantLines => {
            constantLines.Add(); // call methods to configure a constant line
            constantLines.Add();
        })
    )
)
