A scrollbar is an element, that shows a subrange of a fixed interval. It might 
be a good option if you want to scroll long distances. For scrolling in pages 
I'm not sure if it is the right element. As inspiration have a look at the 
event filter example, that scrolls using a QwtWheel - but you could also use 
a QwtPlotPanner disabling the vertical direction.

Anyway you can copy the scroll zoomer class from the realtime example to your 
code and use it as it is.
