void custom()
{
// Create two histograms
TH1F *hpx = new TH1F("hpx","This is the px distribution",100,-4,4);
TH2F *hpxpy = new TH2F("hpxpy","py vs px",40,-4,4,40,-4,4);
// http server with port 8080, use jobname as top-folder name
THttpServer* serv = new THttpServer("http:8080");
// use custom web page as default
serv->SetDefaultPage("custom.htm");
// Fill histograms randomly
TRandom3 random;
Float_t px, py;
// press Ctrl-C to stop macro
while (!gSystem->ProcessEvents()) {
random.Rannor(px,py);
hpx->Fill(px);
hpxpy->Fill(px,py);
}
