Hi,

You need to add the data points in the chart area's data series, as shown here.

<telerik:RadChart.DefaultView>
 <telerik:ChartDefaultView>
  <telerik:ChartDefaultView.ChartArea>
   <telerik:ChartArea>
    <telerik:ChartArea.DataSeries>
     <telerik:DataSeries>
        <telerik:DataPoint XCategory="C1" YValue="5" />
        <telerik:DataPoint XCategory="C2" YValue="10" />
        <telerik:DataPoint XCategory="C3" YValue="8" />

Note that these data points will be taken into account only if items source is not set.
