Compass Plot

Postby cassidyh » Fri Jul 15, 2005 8:13 pm

I am trying to implement a compass where I want to be able to point the needle to changing directions. However it is not clear to me how the compass determines where 0 is. I changed the demo degree to 0 and it points to South, which should be 180 from what I understand. Could someone please shine some light on how the degrees work in the compass plot? I really appreciate all your help
