Detailed Description

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

void ratioplot5() {
auto c1 = new TCanvas("c1", "fit residual simple");
auto h1 = new TH1D("h1", "h1", 50, -5, 5);
h1->FillRandom("gaus", 2000);
h1->Fit("gaus","0");
h1->GetXaxis()->SetTitle("x");
h1->GetYaxis()->SetTitle("y");
auto rp1 = new TRatioPlot(h1);
rp1->SetConfidenceIntervalColors(kBlue, kRed);
rp1->Draw();
}
