Detailed Description

Example that shows how you can set the colors of the confidence interval bands by using the method TRatioPlot::SetConfidenceIntervalColors.

Inspired by the tutorial of Paul Gessinger.

 
import ROOT
 
ROOT.gStyle.SetOptStat(0)
 
c1 = ROOT.TCanvas("c1", "fit residual simple")
h1 = ROOT.TH1D("h1", "h1", 50, -5, 5)
h1.FillRandom("gaus", 2000)
h1.Fit("gaus")
h1.GetXaxis().SetTitle("x")
h1.GetYaxis().SetTitle("y")
 
rp1 = ROOT.TRatioPlot(h1)
rp1.SetConfidenceIntervalColors(ROOT.kBlue, ROOT.kRed)
rp1.Draw()
c1.Update()
