Try this:  

{

TCanvas* c=new TCanvas();

TH1F* hist = new TH1F("hist", "hist", 100, -5, 5);

hist->FillRandom("gaus",10000);

hist->Draw();

hist->Fit("gaus", "", "", -3, 3);

gPad->Update();

TPaveStats *st =

(TPaveStats*)hist->GetListOfFunctions()->FindObject("stats");  

st->SetX1NDC(.2);

st->SetX2NDC(.4);

gPad->Update();

c->Modified();

}

Hi all,

i want to change the position of TPaveStats using codes as follows:

 TCanvas* c=new TCanvas();

    TH1F* hist = new TH1F("hist", "hist", 100, -5, 5);

    hist->FillRandom("gaus",10000);
    hist->Draw();
    hist->Fit("gaus", "", "", -3, 3);
    gPad->Update();

    TPaveStats *st = (TPaveStats*)hist->FindObject("stats");

    st->SetX1(2);
    st->SetY1(300);
    st->SetX2(4);
    st->SetY2(400);

    //st->UseCurrentStyle();
    gPad->Update();
    c->Modify();  

but nothing happens, could you please tell me how to set the position of TPaveStats

Thank you! Received on Mon Mar 21 2011 - 14:38:45 CET
