Action<CollectionFactory<ChartAnnotationConfigBuilder>> configurator
)

---|---|---|

Returns
Type | Description |
---|---|
ChartBuilder | A reference to this instance after the method is called. |
Remarks
To configure an annotation config 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 ChartAnnotationConfigBuilder whose methods you can use to configure an item.
@(Html.DevExtreme().Chart()
.Annotations(annotations => {
annotations.Add(); // call methods to configure an annotation config
annotations.Add();
})
)
