MS Chart in WPF, Setting the DataSource is not creating the Series

Here I am trying to assign the datasource (using same code given in the sample application) and create a graph, only difference is i am doing it in WPF WindowsFormsHost. due to some reason the datasource is not being assigned properly and i am not able to see the series ("Series 1") being created. wired thing is that it is working in the Windows Forms application but not in the WPF one.

am i missing something and can somebody help me?

Thanks

With the following two changes, you can fix your code:

1 - Instead of

Chart1.Series"Series 1".XValueMember = "Name"; 
Chart1.Series"Series 1".YValueMembers = "Sales";

write

Chart1.Series["Series 1"].XValueMember = "Name"; 
Chart1.Series["Series 1"].YValueMembers = "Sales";

2 - Before the above code, insert the following lines:

Chart1.ChartAreas.Add("Default");
Chart1.Series.Add(new Series("Series 1"));
