TGraphBentErrors Class Reference

A TGraphBentErrors is a TGraph with bent, asymmetric error bars.

The TGraphBentErrors painting is performed thanks to the TGraphPainter class. All details about the various painting options are given in this class.

The picture below gives an example:

{
auto c1 = new TCanvas("c1","A Simple Graph with bent error bars",200,10,700,500);
const Int_t n = 10;
Double_t x[n] = {-0.22, 0.05, 0.25, 0.35, 0.5, 0.61,0.7,0.85,0.89,0.95};
Double_t y[n] = {1,2.9,5.6,7.4,9,9.6,8.7,6.3,4.5,1};
Double_t exl[n] = {.05,.1,.07,.07,.04,.05,.06,.07,.08,.05};
Double_t eyl[n] = {.8,.7,.6,.5,.4,.4,.5,.6,.7,.8};
Double_t exh[n] = {.02,.08,.05,.05,.03,.03,.04,.05,.06,.03};
Double_t eyh[n] = {.6,.5,.4,.3,.2,.2,.3,.4,.5,.6};
Double_t exld[n] = {.0,.0,.0,.0,.0,.0,.0,.0,.0,.0};
Double_t eyld[n] = {.0,.0,.05,.0,.0,.0,.0,.0,.0,.0};
Double_t exhd[n] = {.0,.0,.0,.0,.0,.0,.0,.0,.0,.0};
Double_t eyhd[n] = {.0,.0,.0,.0,.0,.0,.0,.0,.05,.0};
auto gr = new TGraphBentErrors(n,x,y,exl,exh,eyl,eyh,exld,exhd,eyld,eyhd);
gr->SetTitle("TGraphBentErrors Example");
