TText and TFrame

Hello everybody,

why this does not print anything on the canvas?

TCanvas* c = new TCanvas("c","c",1); TH1F* h = c->DrawFrame( 1700 , 0 , 2500 , 1.2 ); TText* t = new TText( 0.5 , 0.5 , "Hello World!"); t->Draw();

Thanks.

t->SetNDC(); // root.cern.ch/root/htmldoc/guide … s-of-a-pad
