How to use SetRangeUser

[nab]

Dear developers,

I want to change the x-axis range of my histograms and then stack on each other in range 60-120. I am using the SetRangeUser command but it is not working. Kindly see my script to resolve it.

Thanks.

SetAxisRange(0.0,1.0,"Y"); is ineffective

From my experience … for a TH1 I am usually using something like this: histo->Draw(); histo->SetAxisRange(xmin, xmax, “X”); histo->SetAxisRange(ymin, ymax, “Y”); histo->Draw(); // make sure it’s redrawn If I am dealing with a THStack of several TH1 histograms, I am usually using something like this: stack->Draw(“H”); stack->GetXaxis()->SetLimits(xmin, xmax); stack->SetMinimum(ymin); stack->SetMaximum(ymax); stack->Draw(“H”); // make sure it’s redrawn

Try: h4bprof->SetAxisRange(8, 20, “Z”); and/or: h4bprof->GetZaxis()->SetRangeUser(8, 20); Actually, I believe this should work as well: h4bprof->SetMinimum(8); h4bprof->SetMaximum(20); See also: [url]SetAxisRange(0.0,1.0,“Y”); is ineffective [url]Drawing a TGraphAsymmErrors BTW. You have a typo in your “tree.c” file in line 356 … “SetMinimun” does NOT exist at all (note that the last character in this name is a “n” instead of a “m”) … I think that’s where your problem originates …

SetRangeUser and SetTitle working with THStacks and TH1F obj

I once had similar problems. Here’s what I’ve found to be working (don’t ask me why, no idea). THStack *hs = (THStack *)0; hs = new THStack(*hs_ORIG); // do not modify the "hs_ORIG" THStack, create a copy hs->Draw("H NOSTACK"); hs->GetHistogram()->SetXTitle("My X Title"); hs->GetHistogram()->SetYTitle("My Y Title"); hs->GetXaxis()->SetTitleOffset(1.0); hs->GetYaxis()->SetTitleOffset(1.5); hs->GetYaxis()->CenterTitle(kTRUE); hs->GetXaxis()->SetLimits(0, 10.001); // "xmin", "xmax" hs->SetMinimum(…

Plotting a portion of a histogram?

{ gStyle->SetOptFit(); TH1::SetDefaultSumw2(kTRUE); // ensure proper error propagation TH1D *counts = new TH1D("counts", "full histogram", 100, -5, 5); // counts->Sumw2(kTRUE); // not needed if "TH1::SetDefaultSumw2" counts->FillRandom("gaus", 11000); TH1D *bgcounts = new TH1D("bgcounts", "background", 100, -5, 5); // bgcounts->Sumw2(kTRUE); // not needed if "TH1::SetDefaultSumw2" bgcounts->FillRandom("gaus", 1000); TH1D *noBgCounts = new TH1D(*counts); // make a copy of "count…

Thank you. But I tried all the commands still my histogram is not changing the range.
But when I use hs->SetMinimum(20); it changes the yaxis but i want to change xaxis range.

How to set ranges on axis?

The viewing range for a histogram axis can be set from bin ifirst to ilast using the method TAxis::SetRange(ifirst, ilast). Example (hpxpy is a 2D histogram): { TFile f("hsimple.root"); hpxpy->Draw("colz"); hpxpy->GetYaxis()->SetRange(22,23); hpxpy->GetXaxis()->SetRange(18,19); } Sometimes it is more convenient to set this range using “User’s Coordinates” (axis values) rather than bin numbers. To do that one should use TAxis::SetRangeUser(ufirst, ulast). This method computes the cl…
