Did you know that you can add Telerik Silverlight Charts to your ASP.NET applications?

RadControls for Silverlight


  • This example shows how to add or remove data series and how to customize the X and Y axes. The chart has multiple bar series. The Y axis has a fixed value range. Only item values that fall into this range are shown normally. The others preserve only their labels. The X axis item labels can be changed dynamically.
