How to add slider bar and make 'slice' figure into a GUI to scroll the slice?

My question seems a repeat of this unanswered 2014 question. My goal seems very simple: Be able to scroll the slice back and forward. How do I make xslice, yslice, zslice a value changeable by a scroll bar to scroll the slices back and forward in each axis?

Code:

dose = double(squeeze(dicomread('dose.dcm')));
xslice = [100 140]; 
yslice = 50; 
zslice = 80;
slice(dose,xslice,yslice,zslice)
colormap hsv
xlabel('x, rows')
ylabel('y, cols')
zlabel('z, frames')

I have returned to the App designer documentation and am trying to learn how to use this code in the App Designer.

I added the following code to three slider callbacks. This solution works, but does not allow me more than a single slice at a time, and there is an extraneous empty popup figure window.

            xslice = event.Value;
            yslice = [];
            zslice = [];
            dose = double(squeeze(dicomread('dose.dcm')));
            slice(app.UIAxes,dose,xslice,yslice,zslice)
            colormap hsv

The code is similar for the yslice and zslice callback functions.

I would provide the dose.dcm but it is 0.5 MB above the limit. I tried to attach the mlapp file but it is not an allowed file format.
