Hi Victor, The TAxis::SetRange function expects a bin range. May be it should have been called TAxis::SetBinRange instead. In your example, you are setting the bin range with SetBins. You do not need to call TAxis::SetRange in addition. My guess is that you meant calling TAxis::SetLimits instead of TAxis::SetRange I have protected TAxis::SetRange in case of inconsistent parameters Rene Brun Victor Krylov wrote: > > Hello Rene, > > I have: > ROOT Version 2.23/12 1 February 2000 for linux Radhat 6.1 > SetRange crash macro: > { > gROOT->Reset(); > gROOT->Time(); > > TCanvas c1("c1","Banana Plant Items",1); > TPad p1("p1","p1",0.1,0.1,0.99,0.99); > p1.Draw(); > p1.cd(); > TH1F h1("h1","h1",10,0,10); > //... > h1.SetBins( 10, 101, 110 ); > h1.GetXaxis()->SetRange( 101, 110 ); > //... > h1.Draw(); > > gROOT->Time(); > } > root [0] .x Range.C > Error in <TPad::Range>: illegal world coordinates range: x1=201.125000, > y1=-13125001765323666448603752169472.000000, x2=99.875000, > y2=118125002589728982276512847757312.000000 > Error in <TPad::RangeAxis>: illegal axis coordinates range: xmin=191.000000, > ymin=0.000000, xmax=110.000000, ymax=105000004451182774671796619706368.000000 > > Fatal in <operator new>: storage exhausted > aborting > Aborted (core dumped) > /////////////// > By the way, if I change draw options or change range > of some axis on the screen by hand and then call > SetBins(... for a histogram that we will have unpredictable > results of the axis range on the screen (it reason for using > TAxis::SetRange after calling TH1::SetBins). > Now I call TAxis::SetRange() with default parameters, > it works... > > Regards, > Victor > Phobos/RHIC/BNL > > Rene Brun wrote: > > > Hi Victor, > > I suppose that you mean SetRange and not SetRegion. > > I cannot repdoduce your problem.
