TGraphMultiErrors Class Reference

TGraph with asymmetric error bars and multiple y error dimensions.

The TGraphMultiErrors 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 multiple y-errors", 200, 10, 700, 500);
c1->SetGrid();
c1->GetFrame()->SetBorderSize(12);
const Int_t np = 5;
Double_t x[np] = {0, 1, 2, 3, 4};
Double_t y[np] = {0, 2, 4, 1, 3};
Double_t exl[np] = {0.3, 0.3, 0.3, 0.3, 0.3};
Double_t exh[np] = {0.3, 0.3, 0.3, 0.3, 0.3};
Double_t eylstat[np] = {1, 0.5, 1, 0.5, 1};
Double_t eyhstat[np] = {0.5, 1, 0.5, 1, 2};
Double_t eylsys[np] = {0.5, 0.4, 0.8, 0.3, 1.2};
Double_t eyhsys[np] = {0.6, 0.7, 0.6, 0.4, 0.8};
auto gme = new TGraphMultiErrors("gme", "TGraphMultiErrors Example", np, x, y, exl, exh, eylstat, eyhstat);
gme->AddYError(np, eylsys, eyhsys);
gme->SetMarkerStyle(20);
gme->SetLineColor(kRed);
gme->GetAttLine(0)->SetLineColor(kRed);
gme->GetAttLine(1)->SetLineColor(kBlue);
gme->GetAttFill(1)->SetFillStyle(0);

◆ Allocate()

Double_t ** TGraphMultiErrors::Allocate ( Int_t  size)
protectedvirtual

Definition at line 901 of file TGraphMultiErrors.cxx.

◆ Apply()

void TGraphMultiErrors::Apply ( TF1 f)
virtual

Apply a function to all data points y = f(x,y)

Errors are calculated as eyh = f(x,y+eyh)-f(x,y) and eyl = f(x,y)-f(x,y-eyl) Only the first error dimension is affected!!!

Special treatment has to be applied for the functions where the role of "up" and "down" is reversed. function suggested/implemented by Miroslav Helbich helbi.nosp@m.ch@m.nosp@m.ail.d.nosp@m.esy..nosp@m.de
