Example which shows how you can get the graph of the lower plot and set the y axis range for it.
Since the lower plot is not created until TRatioPlot::Draw
is called, you can only use the method afterwards.
auto c1 =
new TCanvas(
"c1",
"fit residual simple");
auto h1 =
new TH1D(
"h1",
"h1", 50, -5, 5);
rp1->Draw();
rp1->GetLowerRefGraph()->SetMinimum(-2);
rp1->GetLowerRefGraph()->SetMaximum(2);
}

virtual void FillRandom(const char *fname, Int_t ntimes=5000, TRandom *rng=nullptr)
Fill histogram following distribution in function fname.
virtual TFitResultPtr Fit(const char *formula, Option_t *option="", Option_t *goption="", Double_t xmin=0, Double_t xmax=0)
Fit histogram with function fname.
