Hello Andrew,
You can define custom AreaSeries.PointTemplate for each series item and you can also set AreaSeries.ShowLabels property to true to display the series item labels like this:
Also, for Q3 2012 (scheduled around mid-October) we will be introducing support for custom annotations so you will be able to overlay any FrameworkElement on a custom location inside the plot area.
Hope this helps.

You can achieve the desired functionality like this:
public MainPage(){ InitializeComponent(); RadChart1.Loaded += new RoutedEventHandler(RadChart1_Loaded);}private void RadChart1_Loaded(object sender, RoutedEventArgs e){ Dispatcher.BeginInvoke(() => { // Get the data point you want to mark. CategoricalDataPoint dataPoint = (RadChart1.Series[0] as AreaSeries).DataPoints[3]; // Find the corresponding visual by its DataContext property. var ellipsePresenter = RadChart1.ChildrenOfType<ContentPresenter>().Where(presenter => presenter.Opacity != 0 && presenter.DataContext == dataPoint).SingleOrDefault(); if (ellipsePresenter != null) { ellipsePresenter.ChildrenOfType<Ellipse>().Single().Fill = new SolidColorBrush(Colors.Red); } });}Hope this helps.
