Zoom to simply widen the widget on a scroll pane

[Uwe]

I've got a QScrollArea with my Plot widget (which derive from QwtPlot) attached.

Bad idea you will have a horrible performance running out of of memory, when you zoom in deep.
Have a look at the realtime example that uses scrollbars without these problems.

Ohh, right. I forgot that in my case the whole graph would be reploted everytime.
Well, you convinced me, thanks a lot
