Dynamic number of LineSeries in WPF Charting using MVVM

Question

I have gone through lot of sample projects on the net which claim to follow the MVVM pattern and have dynamic number of LineSeries (or) Series objects in a Chart,but rather each one of them just create a wrapper or inherit the Chart class and somewhere call the chart.Series.Add() function to add the series.

I was searching for an example where we have ObservableCollection<ObservableCollection<int,int>> and I bind this List to the Chart.Whenver I add or remove any ObservableCollection from the outer list a Series automatically should get populated.

Thanks in Advance.

I have found this :

http://jmorrill.hjtcentral.com/Home/tabid/428/EntryId/351/Silverlight-Charts-Binding-multiple-Series.aspx

I have ObservableCollection<ObservableCollection<KeyValuePair<int,int>>> ListOfLists and

I set Helper:ChartHelper.SeriesSource="{Binding ListOfList}"

but still it does not work
