We need to dynamically create an XamlDataChart in a WPF application.  The user will click a button to add/remove line series from the chart.  The series are determined dynamically at run time.     

The example below is based on the Getting Started with XamDataChart in the infragistics help.  Is there any reason why it only shows an empty chart?

It is the main window from a newly created WPF application.  C# and XAML are below.

 <Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow"
        Height="400"
        Width="525">
    <Grid  Height="400"
           HorizontalAlignment="Stretch"
           VerticalAlignment="Stretch"
           Background="Aqua">
        <StackPanel x:Name="MyContentPanel"
                    Background="lightyellow"
                    HorizontalAlignment="Stretch"
                    VerticalAlignment="Stretch">

        </StackPanel>
    </Grid>
</Window>
