Hello, I am asking this question to you guys with my dillema
There is a code
TCanvas *hlabels1()
{ float balance[] = {5,6,7,8,9,10,5,5,5,5,5,5,5,5,5,5,5,5,5,5};
const Int_t nx = 20;
const char *people[nx] = {"Jean","Pierre","Marie","Odile","Sebastien",
"Fons","Rene","Nicolas","Xavier","Greg","Bjarne","Anton","Otto",
"Eddy","Peter","Pasha","Philippe","Suzanne","Jeff","Valery"};
TCanvas *c1 = new TCanvas("c1","demo bin labels",10,10,900,500);
c1->SetGrid();
c1->SetTopMargin(0.15);
TH1F *h = new TH1F("h","test",3,0,3);
h->SetStats(0);
h->SetFillColor(2);
//h->SetCanExtend(TH1::kAllAxes);
for (Int_t i=0;i<10;i++) {
h->Fill(people[i],balance[i]);
}
h->LabelsDeflate();
h->Draw();
TPaveText *pt = new TPaveText(0.7,0.85,0.98,0.98,"brNDC");
pt->SetFillColor(1);
pt->SetTextAlign(12);
pt->AddText("Use the axis Context Menu LabelsOption");
pt->AddText(" \"a\" to sort by alphabetic order");
pt->AddText(" \">\" to sort by decreasing values");
pt->AddText(" \"<\" to sort by increasing values");
pt->Draw();
return c1;
}
This code obviously give me a funky plot (The color of histogram not being filled)
since Fill should be used as Fill->(people[i],1)
However, I can not replace that with SetBinContent since I want x-axis as char variable.
Could I know a way
To fill TH1F with char variable x-axis with an array of float variable as BinContent?
Thank you!
