Can't put TPaveStats box on a histogram

[couet]

@Wile_E_Coyote

Note that if you execute the monopoles->Draw(“… >> MyHisto”) command two times or more (in a row), starting with the second pass, it will draw the statistics box (without any need for an additional “drawing option”).

Yes because at the 2nd execution the histogram already created. I works also without drawing option if you create the histogram before doing TTree::Draw.

root [0] TH2F *h2 = new TH2F("h2","h2",10,-10,10,10,-10,10)
root [1] ntuple->Draw("px:py>>h2")
