Hi,
I want to create a TGraphError object and then save it in file "graph.root" . Iam trying to do as follows(but no luck):


{
TFile f("graph.root","recreate");
float flux[7]={1.06e6,2.97e5,1.36e5,4.11e4,2.29e4,7.56e3,5.22e3}; float flux_err[7] = {0.92e2, 0.31e3, 0.64e3, 3.33e3, 0.36e3, 0.84e3, 0.28e1}; float rad[7]={4.1, 7.2, 11.1, 23.4, 34.5, 61, 108}; float rad_err[7]={0,0,0,0,0,0,0};
TGraph *gr2 = new TGraphErrors(7,rad, flux,rad_err,flux_err); gr2->Draw("A*");

f.cd();
f.Write();
f.Close(); 

}

Any help would be appreciated
