This example shows:

  • how to remove a stat element from the stat box
  • how to add a new one
{
// Create and plot a test histogram with stats
TCanvas *se = new TCanvas;
TH1F *h = new TH1F("h", "test", 100, -3, 3);
h->FillRandom("gaus", 3000);
h->Draw();
se->Update();
// Retrieve the stat box
TPaveStats *ps = (TPaveStats *)se->GetPrimitive("stats");
ps->SetName("mystats");
// Remove the RMS line
TText *tconst = ps->GetLineWith("RMS");
listOfLines->Remove(tconst);
// Add a new line in the stat box.
// Note that "=" is a control character
TLatex *myt = new TLatex(0, 0, "Test = 10");
myt->SetTextFont(42);
myt->SetTextSize(0.04);
myt->SetTextColor(kRed);
// the following line is needed to avoid that the automatic redrawing of stats
h->SetStats(0);
se->Modified();
return se;
