Programmatically add dvt:annotation(s) on a bar graph

Question

I have a dvt:barGraph that uses the BAR_VERT_STACK subType.
I am building the data/model via a backing bean method. This seems to work fine.
At this point, I want to add annotations to specific “cells” within the bar(s).
However, I am not sure how to programmatically do this (add dvt:annotation(s) to my graph).
For example, I would like to call a method and have the [Group=1,Series=0] and [Group=2,Series=3] cells have the annotation "*".
Any suggestions?
Thanks

You can try to bind graph component to bean and use something like:
Annotation annotation = new Annotation();
annotation.setSeries(0);
annotation.setGroup(0);
annotation.setText("My text");
Map annotationMap = graphComp.getAnnotationSet().getAnnotationMap();
if(annotationMap == null){
    annotationMap = new HashMap();
    graphComp.getAnnotationSet().setAnnotationMap(annotationMap);
annotationMap.put(0, annotation);
AdfFacesContext.getCurrentInstance().addPartialTarget(graphComp);Dario
