TGraph and log scale

ROOT
1

Hello,

I am plotting with TGraph. I cannot figure out to set a logarithmic scale on the y axis and set a minimum and maximum values on the x and y axis.
Somebody can help ?
Cheers.

lin/log scale is a property of the pad/canvas, not of the object that can be drawn in lin scale in one pad and log scale in another pad. To answer your question, do

TCanvas c1; c1.SetLogy(); gr->SetMaximum(max); gr->SetMinimum(min); gr->Draw("alp");
