I'm programming a PID (GUI) for a control system, but I have problems with the sliders. I can not make the graph updates as you move the slider.
I have to do that every time the slider is moved to update the graphics, without pressing any additional buttons.

You need to insert a plot function inside a slider function callback.

Yes, the problem is that the data is not updated automatically.
e.g.
slider1_Callback function (hObject, eventdata, hand .... h = get (handles.slider1, 'value') sys = feedback (sys, h) axes (handles.axes1) rlocus (sys) grid on
But when you move the slider the graph does not change.
