Try these WPF & Silverlight chart controls.. http://www.visifire.com/
I've been using Visifire for a year now and an SL3 app and it worked very well. You just feed it arrays of data series and points and it produces impressive charts with little effort. We even drilled down and adjusted the shapes of data points, series colours, etc with the countless properties. We're upgrading to C1 charting now, mainly because it has radar charts, which are curiously missing from Visifire. Greg
