Above works fine.
Small follow up question if I may.
Can I set this value in the markup (or even server side code??).
eg: in here?
<Pointer Value="0" Color="255, 200, 30">
<Cap Color="255, 200, 30" />
At the end of the day, I do have jscript code to set above working, but if I can set this server, or client side without code, then I not have to setup a hidden control to hold the gauge value, set duration speed, and then set gauge value.
