flex - Adding annotations to a PlotChart -

I'm looking to add text annotation (and delete, dynamic) to PlotChart. Especially I want to annotate plot points in the chart. I am currently using Circle ITEM Renderer for points.

I have found a tutorial for other conspiracy types, but they are not applying to Plotchart.

Someone has an example, or can point me in the right direction.

The usual way to do this kind of thing is to add an example of the Cartesian data cast, Property This line is for charts, but the principle is similar to any Cartesian chart.

Here also one.
