QwtZoomer problem when I change axis scale [SOLVED]

Hi,
I have a plot of some data, with a zoomer and a panner.
Every time I click a button I reset the data of the curve and also I change the x axis scale.
The problem is the zoom out of the Zommer: it restores the first x axis scale that I've set. But this is no longer valid for the current chart.

I've read this post: http://www.qtcentre.org/forum/f-qwt-...lot-13012.html
I don't understand what should I do.

Thanks

When you change the axes behind the back of the zoomer, you have to reinitialize it with zoomer->setZoomBase().
