Add TProfile to TMultigraph

Dear all.
Is it possible to add a TProfile to a TMultiGraph?

The example below doesnt work unfortunately…

int addPtoMG(){
TCanvas c1 = new TCanvas(“c1”,“Profile histogram example”,200,10,700,500);
TProfile
hprof ;
hprof = new TProfile(“hprof”,“Profile of pz versus px”,100,-4,4,0,20);
Float_t px, py, pz;
for ( Int_t i=0; i<25000; i++) {
gRandom->Rannor(px,py);
pz = pxpx + pypy;
hprof->Fill(px,pz,1);
}
hprof->Draw();

TProfile* hprof2 ;
hprof2  = new TProfile("hprof2","Profile of pz versus px2",100,-4,4,0,20);
for ( Int_t i=0; i<25000; i++) {
	gRandom->Rannor(px,py);
	pz = 0.5*px*px + 0.5*py*py;
	hprof2->Fill(px,pz,1);
}
hprof2->SetLineColor(2);
hprof2->Draw("same");

TMultiGraph* mg = new TMultiGraph();
mg->Add(hprof,"apl");

return 0;

}

Processing addPtoMG.C…
Error: Can’t call TMultiGraph::Add(hprof,“apl”) in current scope addPtoMG.C:22:
Possible candidates are…

Thanks for your help

No.

A TMultiGraph is a collection of TGraphs.
