    Hi, is it possible to bind to a DataSeriesCollection, something along these lines:

    private DataSeriesCollection _chartDataSeries;
    public DataSeriesCollection ChartDataSeries
        get { return _chartDataSeries ?? (_chartDataSeries = new DataSeriesCollection()); }
            if (_chartDataSeries == value) return;
            _chartDataSeries = value;
            NotifyPropertyChanged(() => ChartDataSeries);
    public void AddDataSeries(DataSeries series)

    with the dataseries being created like this:
    public Type TargetSeriesDefinition { get; set; }
    public DataSeries GetDataSeries(IEnumerable<StudyData> points, string label)
        SeriesDefinition seriesDefinition = null;
        if (TargetSeriesDefinition != null)
            if (TargetSeriesDefinition.FullName != null)
                seriesDefinition = TargetSeriesDefinition.Assembly.CreateInstance(TargetSeriesDefinition.FullName) as SeriesDefinition;
        if (seriesDefinition == null) return null;
        seriesDefinition.ItemStyle = Application.Current.Resources["DragAndDropItemsStyle"] as Style;
        seriesDefinition.Appearance.Cursor = Cursors.Hand;
        var series = new DataSeries()
                             Definition = seriesDefinition,
                             LegendLabel = label
        points.ToList().ForEach(point => series.Add(new DataPoint{ XValue = point.Date.ToOADate(), YValue = point.Value}));
        return series;

    The scenario I am  trying to support is manually creating the series based on a stringvalue being dropped onto the chart, as well as being able to drag serioes between different charts, combined with the ability to dynaimcally select the type of series to be displayed on each chart. I cant do it in codebehind because the charts are instantiated via a datatemplate as part of an itemscontrol.

    I tried:
    <Charting:ChartArea ItemsSource="{Binding ChartDataSeries}" >

    <Charting:ChartArea Series="{Binding ChartDataSeries}" >

    but both throws exceptions.
    <Charting:ChartArea ItemsSource="{Binding ChartDataSeries}" >

    <Charting:ChartArea ItemsSource="{Binding ChartDataSeries}" >
