Hi ROOTers,

In the User's Guide it is said that to zoom a graph you have to create an 
empty histogram with the axis limits you want, and then draw the graph. Is 
it possible to draw a graph and then reset the axis limits so as to get it 
zoomed?

I mean, I want to first draw the graph, then resize it. I have tried with 
theGraph->GetXaxis()->SetRangeUser(), and then theCanvas->Update(), but it 
doesn't work. Any idea?

Thanks for your help,
