Adding new Elements to the Statistic Box

Roofit and RooStats
1

Hi, I have the following Problem. In my Canvas I displayed several histograms each with a statistic box. I then added a self written class called DoubleList to calculate the percentiles (1%, 2%, 5%, 10%). Additionally to the black percentile lines I am drawing at their position, I would like to add the corresponding value to the statistic box. I tried to follow the path in

https://root.cern.ch/doc/master/classTPaveStats.html

without any success. How can I integrate the freshly computed percentiles in the statistic box?
Kind regards Jim

Replace:

TPaveStats *s4 = (TPaveStats*)h4->GetListOfFunctions()->FindObject("stats");
// ...
s4->Draw();

with:

TPaveStats *s4 = (TPaveStats*)h4->GetListOfFunctions()->FindObject("stats");
s4->SetName("h4_stats");
h4->SetStats(0);
TList *lol = s4->GetListOfLines();
TLatex *ltx = 
  new TLatex(0, 0, TString::Format("1%% = %g", OnePercent4.getValue()));
ltx->SetTextFont(42); ltx->SetTextSize(0.03); ltx->SetTextColor(1);
lol->Add(ltx);
ltx = new TLatex(0, 0, TString::Format("2%% = %g", TwoPercent4.getValue()));
ltx->SetTextFont(42); ltx->SetTextSize(0.03); ltx->SetTextColor(1);
lol->Add(ltx);
ltx = new TLatex(0, 0, TString::Format("5%% = %g", FivePercent4.getValue()));
ltx->SetTextFont(42); ltx->SetTextSize(0.03); ltx->SetTextColor(1);
lol->Add(ltx);
ltx = new TLatex(0, 0, TString::Format("10%% = %g", TenPercent4.getValue()));
ltx->SetTextFont(42); ltx->SetTextSize(0.03); ltx->SetTextColor(1);
lol->Add(ltx);
s4->SetLineColor(1);
s4->SetX1NDC(0.78);
s4->SetX2NDC(0.98);
s4->SetY1NDC(0.48);
s4->SetY2NDC(0.18);
c->Modified();
// s4->Draw();

Thanks for the quick replay but as I mentioned in my text I already tried that.
My command with s4->Draw(); where I am drawing the StatBox does not go well with h4->SetStats(0);
So how do I do that correctly, here is my “not working” version.

I get many errors when I run your macro:

Thank you very much, this is exactly what I needed :slight_smile:
