Hi,I wonder if is it possible to programme a speed trend gauge in xml ?BrgdsEuge

Eugen, Here's one that works for our EADI.. Probably could be written better but hey.... It works :-)(P:Local Time, seconds) 0.2 % 10 * int 0 == if{ (A:Airspeed indicated, knot) (>G:Var1) }(P:Local Time, seconds) 0.2 % 10 * int 1 == if{ (A:Airspeed indicated, knot) s1 (G:Var1) - 0.1 / 10 * l1 + (>G:Var3) }(G:Var3) (A:Airspeed indicated, knot) >(A:Airspeed indicated, knot) 45 < if{ 0 } els{ (G:Var3) (A:Airspeed indicated, knot) - }(G:Var3) (A:Airspeed indicated, knot) <(A:Airspeed indicated, knot) 45 < if{ 0 } els{ (G:Var3) (A:Airspeed indicated, knot) - }Regards,Roman[link:www.packers.com]GREEN BAY PACKERS][/i :-ukliam :-beerchug

Thanks Roman!After some fixing I got it to work with my images,is it 10 sec that is the range?BrgdsEugen

Glad it works for you too.. Yep, it is a 10 second calculated trend with samples taken every 0.1 second. The pixelspersecond @ 10 just smooths it out a bit. Regards,Roman[link:www.packers.com]GREEN BAY PACKERS][/i :-ukliam :-beerchug
