Re: How to set range of y-axis for THStack?

Ok that's index something specify to the stack. When I do the following I do not see the same effect. I will check:

root [0] gStyle->SetHistTopMargin(0.);
root [1] hpx->Draw()
root [2] hpx->SetMinimum(100)
root [3] hpx->SetMaximum(600)
root [4] hpx->Draw()
root [5] hpx->GetYaxis()->SetMoreLogLabels();

But You can bypass it ...
The attached macro gives you an other way to do want you are looking for.
