Can anyone provide a XamWebRadialGauge template that uses only a half circle, rather than the full ellipse?  I've tried using a Path and setting the start and end angle on the gauge to 180,360 but the control still centers around what the full ellipse would be and then my path shows up in the middle of that, so I can't get things to align correctly. 

Here's my attempt below.  Any help would be much appreciated.

Thanks,
Keith
