Hi rooters,
this might be more a C++ beginners problem, but i cant
figure out why this crahses
void DrawGraph(RowNr)
{
Double_t* x=new Double_t(NrColumns);
Double_t* y=new Double_t(NrColumns);
for(Int_t i=0;i<NrColumns;i++)
{
x[i]=i;
y[i]=GetRow(RowNr)->At(i);
}
TGraph* Graph=new TGraph(NrColumns,x,y);
delete [] x; // CRASH HERRE !! if i dont delete crash
in the next method call !
delete [] y;
}
It works FINE when I use x/y as stack objects but i do
not know in advance the nr of datapoints !!!
Joe
