Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts

Declaration

C#

public int Add(
    Annotation annotation
)

) As Integer

Parameters

Name	Type	Description
annotation	Annotation	An Annotation class descendant to append to the collection.

Returns

Type	Description
Int32	An integer value indicating the position at which the new element was inserted.

Remarks

The Add method adds TextAnnotation and ImageAnnotation objects to a chart control’s AnnotationRepository, where all annotations that are present in a chart control can be centrally accessed (via the ChartControl.AnnotationRepository property).

Alternatively, you can add annotations directly to an element’s annotations collection, via its AnnotationCollection.AddImageAnnotation or AnnotationCollection.AddTextAnnotation method.

For more information, refer to Annotations.
