Unfortunately, wpfgauge at codeplex uses LGPL license, which makes it unfriendly to businesses that do not wish to release their source code.
dashboarding at codeplex seems nice, but it uses a non-standard way of doing UserControl: There is a control hierarchy deriving from UserControl, so Visual Studio doesn't know how to display controls in the designer. They work at run-time, but it is hard to tweak them in Visual Studio.
