I want to ask is it possible to draw many plots (means the total hight of plots is larger than window size) in scroll area and I also can use mouse to scroll down instead of zooming axis.

"many plots" do you mean multiple graphs?
if you do, yes you can:
plot->addGraph(INDEX);
plot->graph(INDEX)->setData(x,y);
For scroling eg.:
plot->setInteractions(QCP::iRangeDrag | QCP::iRangeZoom | QCP::iSelectPlottables);
