I am trying to add two histograms that I generated with TTree::Draw. The
commands I typed are as follows:
TFile f("atlfast.root");
TTree *t1 = (TTree*)f.Get("Atlfast/50");
t1->Draw("APHOE>>h1");
t1->Draw("BPHOE>>h2");
h1->Add(h2);
When I attempt to add the histograms I get the following:
Error: Symbol h2 is not defined in current scope
FILE:/tmp/filewYtM0M_cint LINE:1
*** Interpreter error recovered ***
Why is h2 not defined in current scope? For that matter what is the
current scope? My knowledge of C++ is quite rudimentary so excuse me if
the answer to this is obvious.
