Adding Multiple Series to a Radchart

[Ram]

Hi All

I have a List<> which contains multiple items and  is built at dynamically when a user clicks Search.

I need to bind this list to a Radchart programmatically and need to add each item in this list to a series then add this to the
Radchart.

I have tried with the code below but i am getting an error - can anyone help?

foreach (ProductsAndPrices yl in YearlyAverage)
{
       string name = yl.Product + " " + yl.ProductStrength + " " + yl.Pack_Size;
       chart.Name = name;
       int av = int.Parse(yl.Average.ToString());
       chart.AddItem(int.Parse(yl.Average.ToString()), name);
}

testing.Series.Add(chart);

I need to get all the values from the list in the format yl[0].Average , yl[1].average etc etc and bind this to the radchart...

Many thanks
Ram
