Hello, I am trying to draw a graph and a function at the same canvas, but I can only see the graph. The option “same” is not working. Can somebody please help me?
This is my code:
{
TGraphAsymmErrors *grae = new TGraphAsymmErrors(42);
grae->SetName("gr_exp1");
grae->SetTitle("AMS02(2011/05-2012/12)");
grae->SetFillColor(1);
grae->SetFillStyle(0);
grae->SetMarkerStyle(2);
grae->SetMarkerSize(1.2);
grae->SetPoint(0,10.33,0.0519);
