GUI - Slider which has two slide bars

Hi,
I'm creating a GUI to help me post-process some sample data collected from an eye tracker. I would like to use a slider to specify a start and end point of sample data I am interested in. To do this it would be useful to have a slider with two slide bars, one which identifies the beginning and end of the interest interval.
Is this at all possible?
James

This functionality is not supported by the inbuilt slider, but you could look at using this FEX submission:
It looks like it allows you to specify multiple sliders.

Thanks Stephen. I'll try out the FEX submission!

You would have to use two sliders - that's what I do. Or have the user manually draw the region with rbbox().

Thanks Image Analyst. I'll try that if I'm not able to get the FEX submission to work.
Well you can either
  1. place two sliders on your existing GUI and be done with it, or
  2. you can take her FEX GUI, delete dozens of sliders that she put on there that you don't need, and then transfer all of your other controls/widgets from your GUI and transfer all the code associated with them to her GUI.
I know which approach I'd take.

Unfortunately this "approach" does not include actually reading the description or documentation of Danielle Ripsman's SuperSlider.
While the screenshot for the submission shows many different possibilities of what can be created using this function, these are shown merely as examples of its capabilities, as the demo code clearly clarifies. The function itself simply creates one single slider, with a selectable number of slider bars, and is called and used in much the same way as a uicontrol slider.
Nor is it required to "transfer all the code" or indeed perform any of the things that you state in your criticism. I just created a single two-bar slider with this code, from the command line:
superSlider('position',[0.1,0.1,0.8,0.1],'numslides',2)
While I have not tested it exhaustively, it seems to perform as its documentation states.
Accusations of writing useless bloatware is rather unkind, and beneath someone of your status on this forum. It misleads other browsers who might read this thread and who would then decide, based on your incorrect assumptions, that Danielle Ripsman's perfectly adequate submission is not worth considering. If someone wants two slider bars, that submission neatly achieves that goal.

Maybe you meant a Range Slider which you can create as shown in Sliders in Matlab GUI .
