WPF Charts for OLAP Cubes

Does anyone know whether there is any charting library or a way to integrate OLAP capabilities to charts done in WPF? What I want is to give a user an option to build charts o开发者_运维百科n an OLAP cube by giving a specific MDX query he/she may wish and drill down the chart to explore the data.

Radarsoft has a set of components including an OLAP Grid and an OLAP Chart for WPF. I haven't used it myself, I only worked with the ASP.NET variant. But I think there is a trial version so you can see if it works out for you.
