How can I actually add (for example) mean value of h histogram in TLegend. I did this:
TH1F *h = new TH1F(*hist);
double mean = h->GetMean();
auto legend = new TLegend(0.1,0.7,0.48,0.9);
legend->AddEntry(h, "data", "l");
legend->AddEntry(mean, "Mean value", ""),
But it`s not working
legend->AddEntry((TObject*)0, TString::Format("Mean value = %g", h->GetMean()), "");
Thanks a lot
