Designing a Slider

Suppose you want to create a slider with the following behavior:

• Slider range = 5 to 8
• Arrow step size = 0.4
• Trough step size = 1
• Initial value = 6.5

From these values you need to determine and set the Max, Min, SliderStep, and Value properties. You can do this by adding the following code to the initialization section of the GUI M-file (after the creation of the handles structure):

• slider_step(1) = 0.4/(8-5);
  slider_step(2) = 1/(8-5);
  set(handles.slider1,'sliderstep',slider_step,...
        'max',8,'min',5,'Value',6.5)

You can also assign the slider properties using the Property Inspector:

• SliderStep, X .133
• SliderStep, Y .333
• Max 8
• Min 5
• Value 6.5
