How can i use TF1::GetHistogram() without drawing the function (using 
TF1::Draw()) ?

If i do not use draw() i get the following error:

root [13] TF1 *func = new TF1 ( "func" , "x" , 0 , 1 ) ;
root [14] TH1D *histo = func -> GetHistogram ( ) ;
root [15] histo -> Draw ( ) ;
Error: illegal pointer to class object histo 0x0 148  FILE:(tmpfile) LINE:1
*** Interpreter error recovered ***
