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);

AddYError()

void TGraphMultiErrors::AddYError ( Int_t  np, const Double_t *  eyL = nullptr, const Double_t *  eyH = nullptr  )

virtual

Add a new y error to the graph and fill it with the values from eyL and eyH.

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
