TGraph2DAsymmErrors Class Reference

Graph 2D class with errors.

A TGraph2DAsymmErrors is a TGraph2D with asymmetric errors. It behaves like a TGraph2D and has the same drawing options.

The **"ERR"** drawing option allows to display the error bars. The following example shows how to use it:

{
auto c = new TCanvas("c","TGraph2DAsymmErrors example",0,0,600,600);
Double_t P = 6.;
Int_t np = 200;
Double_t *rx=0, *ry=0, *rz=0;
Double_t *exl=0, *exh=0, *eyl=0, *eyh=0, *ezl=0, *ezh=0;
rx = new Double_t[np];
ry = new Double_t[np];
rz = new Double_t[np];
exl = new Double_t[np];
exh = new Double_t[np];
eyl = new Double_t[np];
eyh = new Double_t[np];
ezl = new Double_t[np];
ezh = new Double_t[np];
auto r = new TRandom();
for (Int_t N=0; N<np;N++) {
rx[N] = 2*P*(r->Rndm(N))-P;
ry[N] = 2*P*(r->Rndm(N))-P;
rz[N] = rx[N]*rx[N]-ry[N]*ry[N];
rx[N] = 10.+rx[N];
ry[N] = 10.+ry[N];
rz[N] = 40.+rz[N];
exl[N] = r->Rndm(N);
exh[N] = r->Rndm(N);
eyl[N] = r->Rndm(N);
eyh[N] = r->Rndm(N);
ezl[N] = 10*r->Rndm(N);
ezh[N] = 10*r->Rndm(N);
}
auto g = new TGraph2DAsymmErrors(np, rx, ry, rz, exl, exh, eyl, eyh, ezl, ezh);
g->SetTitle("TGraph2D with asymmetric error bars: option \"ERR\"");
g->SetFillColor(29);
g->SetMarkerSize(0.8);
g->SetMarkerStyle(20);
g->SetMarkerColor(kRed);
g->SetLineColor(kBlue-3);
g->SetLineWidth(2);
gPad->SetLogy(1);
g->Draw("err p0");
