Set the value property of it, after you've set up the max and min properties of course.

set(handles.slider1, 'Min', theMinValue);
set(handles.slider1, 'Max', theMaxValue);
set(handles.slider1, 'Value', theCurrentValue);

And add a "drawnow" to update the figure.

thank for answer

however, this code just jump to exactly value. So can i see data scrolls?

[Walter Roberson]

You would have to set to intermediate values. Be sure to drawnow() to update the display afterwards.

hang on,i will describe briefly about my problem. I have sample data of EEG, I already read, plot, and using slider to view data in short period at the windows. so now i want to autorun slider while i view data.Please explain more your way, and how to apply in my situation. thanks!

Please explain more your way first. What do you mean by autorun slider? Do you want to scroll some data as the user clicks the arrows on the ends of the slider? Or do you want it to move every second or so via a timer? If so see my timer code I posted yesterday.

[Hoang Ton]

i mean that, instead of clicking the arrows on the end of the slider, i just create button play/pause to control this action. when i click that button the data will auto-scroll like i click the arrows, and when i click that button again, scrolling will stop.Thanks!

Start a timer function. It updates the Value of the slider, and calls the slider callback.

cb = get(handles.MySlider,'Callback');

cb{1}(handles.MySlider,[])

When the stop button is pushed, stop the timer.

I use sliders/scrollbars in GUIDE all the time. If yours doesn't work, attach your .fig and .m file in a new question.
