Hi Matej,

The frame does not have access to the Axis objects.  Instead DrawFrame
creates a TH1F named hframe who does have access to the Axis.  This TH1F
object's address is returned by DrawFrame.  Hence you can do:

   pad1 = new TPad("pad1","This is pad1",0.02,0.02,0.98,0.98,33);
   pad1->SetFillColor(10);
   TH1F* histo = pad1->DrawFrame(-0.5,170,10.5,360);
   histo->GetXaxis()->SetTitle("test");
   TFrame *frame= pad1->GetFrame();
   frame->SetFillColor(10);

Cheers,
Philippe.

Hi, there!

I have two graphs on different ranges, so I create pad with frame in
order to get them both printed out. The problem arises when I want to
set titles to the axes. What I do is:

pad1 = new TPad("pad1","This is pad1",0.02,0.02,0.98,0.98,33);
pad1->SetFillColor(10);
pad1->DrawFrame(-0.5,170,10.5,360);
TFrame *frame= pad1->GetFrame();
frame->SetFillColor(10);

This works. The problem arises when I try something similar to

frame->GetXaxis()->SetTitle("test");

Any idea?

Thanks,
Matej
