Hi there,
I want to use the scroll wheel in a figure. What I for instance want: Take the function f(x) = x^a, where 'x' is something like 1:10 and 'a' a constant. I want to plot f(x), and when I scroll up I want 'a' to increase by one, and when I scroll down I want 'a' to decrease by one and display it right away. Is this possible?
Thank you for your help in advance.
Kind regards, Rudy

Some explanation would be nice.

Set a WindowScrollWheelFcn callback on the figure; see http://www.mathworks.com/help/matlab/ref/figure-properties.html for more information on the Event structure that is passed to it.
Your callback would calculate a new value for "a" and then would call a function to do the plotting for you.
