Hi Bernd,
This is not implemented, but you can easily get this functionality
with a few additional lines of code. See example below.
Rene
void marks () {
TFile *f = TFile::Open("hsimple.root"); //from tutorials
TTree *ntuple = (TTree*)f->Get("ntuple");
Int_t n = ntuple->Draw("py:px","pz/5","a");
TMarker *m;
for (Int_t i=0;i<n;i++) {
m = new TMarker(ntuple->GetV1()[i],ntuple->GetV2()[i],24);
m->SetMarkerSize(ntuple->GetW()[i]);
m->Draw();
}
}
