Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v22.2.dll

NuGet Package: DevExpress.Charts


public ImageAnnotation AddImageAnnotation()


Type Description

An ImageAnnotation object representing the image annotation to be added.


This method adds an ImageAnnotation object with the default settings to the annotations collection of a chart, pane or series point.

To add an image annotation with the specified options, use the overloaded AddImageAnnotation methods with the name and image (or, imageUrl) parameters.

After an annotation is added to an element’s collection, it can be accessed via the corresponding property of this element (ChartControl.Annotations, XYDiagramPaneBase.Annotations, or SeriesPoint.Annotations). Alternatively, to centrally access all annotations that are present in a chart control, use the ChartControl.AnnotationRepository property.

When you use the AddImageAnnotation method to add annotations to the XYDiagramPaneBase.Annotations or SeriesPoint.Annotations collections, this automatically anchors the annotation to the pane or the series point (the annotation’s AnchorPoint property is initialized with a PaneAnchorPoint or SeriesPointAnchorPoint object).

For more information, refer to Annotations.
