Using Bound data for X Axis tickpoint labels

[Chet]

In all the examples I've seen for this, the labels for the X Axis tickpoints are applied in the the code behind file (usually in a loop statement).  I'd rather use a binding XAML but I'm having trouble getting the XAML syntax correct for my radchart control. 

For instance, in a collection with two fields, statename, and population, I'd like the XAxis tickpoint labels to be the statenames.  In my mind it would be something like:

<telerik:RadChart.DefaultView>                 
  <telerik:ChartDefaultView>                     
    <telerik:ChartDefaultView.ChartArea>                         
      <telerik:ChartArea>                             
        <telerik:AxisX>                                 
          <telerik:AxisX.TickPoints>                                     
            <telerik:TickPoint Label="{Binding statename}"></telerik:TickPoint>                                 
          </telerik:AxisX.TickPoints>                             
         </telerik:AxisX>                         
      </telerik:ChartArea>                     
    </telerik:ChartDefaultView.ChartArea>                 
  </telerik:ChartDefaultView>             
</telerik:RadChart.DefaultView>

But I always get this error: Set property 'Telerik.Windows.Controls.Charting.BaseFormattableData.Label' threw an exception. [Line: 63 Position: 62]

Anybody able to see what I'm doing wrong?

Thanks,

Hello Chet,

Check this help topic here to get you started with creating categorical charts -- basically you need to bind your business object StateName field to DataPointMember.XCategory when describing the series mapping.
