Ritesh,

The only thing you have to do in order to bind the Series to IList<Data> or any other collection implementing IEnumerable interface is to set the DataSource and the DataMapping. You can refer to our online documentation for more details :

(http://help.infragistics.com/Help/NetAdvantage/WPF/2009.1/CLR3.X/html/xamChart_Binding_xamChart_to_a_Collection.html)

void Window1_Loaded(object sender, RoutedEventArgs e)
        {
            IList<Data> list=new List<Data>();

            Data d1 = new Data() { Type = "T1", Count = 20 };
            Data d2 = new Data() { Type = "T2", Count = 30 };
            ...

            list.Add(d1);
            list.Add(d2);
            ...

            Series s = new Series();
            s.ChartType = ChartType.Pie;
            s.DataSource = list;
            s.DataMapping = "Value=Count;Label=Type";

            xamChart1.View3D = true;
            xamChart1.Series.Add(s);
        }

Let me know if you have any questions with this matter.

Regards
