Hello, I just switched from 3.03/9a to 3.04/2 on Win32. The following simple script displays differently in the two versions: { gROOT->Reset(); TCanvas *pc = new TCanvas("pc","an example",1,5,800,500); pc->Divide(2,1); pc->cd(1); TH1F *ph = new TH1F("ph","demo",100,-25.,25.); ph->FillRandom("gaus",10000); ph->Fit("gaus","wq"); pc->cd(2); gPad->SetLogy(1); ph->Draw(); } In version 3.03/9a, the y-limts in log mode are about 2 to 2000 In version 3.04/02, the y-limits in log mode are something like 10^-125 to 2000 with multiple y-scales drawn. Note: if I draw just the histogram (not the fit), the y-axis limits look the same in logy for both versions.. Ed Oltman
