Similar functions are available for other such scales...PiScale and LogScale come to mind (although they do not take a third argument and should be passed directly into Ticks). Check out Vol. 5, Iss. 2 of the Mathematica Journal (pages 42-4) for more information. -John ==== [MESSAGE SEPARATOR] ====
