Zoom option for moving images

Hi all,

I have created GUI in which real time datas are collected and plotted. So my figure(image) is updated everytime.

I want to set Zoom option. How to do that?

I created Slider option and added following after imshow: ZoomFactor=get(Slider1,'Value'); get(gca); zoom('out') zoom(ZoomFactor)

Is this correct?

Anyone have an idea?

Thanks in advance.
