ROOT is the main analysis/monitoring tool

Phenix has selected ROOT as the main analysis tool for the analysis and the online monitoring. We show here a scenario like this:

{

gSystem->Load("$EVT_LIB/libEvent.so");

h1f = new TH1F("h1f","Test random numbers",100,-49.5,50.5);

Eventiterator *it = new ddEventiterator("online");

int i;

for (i=0; i򓍸 i++)

{

Event *e = it->getNextEvent();

Packet *p = e->getPacket(1003);

h1f->Fill(p->iValue(0));

delete p;

delete e;

}

delete it;

h1f->Draw();

}
