)

configurator	Action<CollectionFactory<PieChartAnnotationConfigBuilder>>	A function that allows you to specify nested options.

Returns

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

Remarks

To configure an annotation 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 PieChartAnnotationConfigBuilder whose methods you can use to configure an item.

Razor C#

@(Html.DevExtreme().PieChart()
    .Annotations(annotations => {
        annotations.Add(); // call methods to configure an annotation item
        annotations.Add();
    })
)
