When you install RadControls for Silverlight the installer adds an icon for the sparklines in the Visual Studio toolbox. All you have to do is drag a sparkline from the toolbox and drop in in your application. This will add all needed assemblies to your project and also proper namespace declarations to your XAML.
Alternatively you can do this on your own by adding reference to this assemblies:
Next add a namespace declaration in the page where you want your sparklines placed:
Finally add the sparklines by using the namespace above as a prefix:
<telerik:RadLinearSparkline Name="Sparkline" />
You can find more informations on sparklines in our help system here
Hope this helps!
All the best,
the Telerik team
