You can bind the control to any IEnumerable ItemsSource and that includes nested collections
(collection of collections) in XAML but generally you would also need to set up the necessary series mappings as well and this cannot be done statically in XAML if you do not know the number of series you will be displaying in the chart control.
Alternatively, you can use the databinding with automatic series mappings
feature provided by RadChart as well but you will need a specially-crafted business object that contains all necessary numeric fields that should be displayed as chart series.
