Please pay your attention for the $ROOTSYS/tutorials/ntuple1.C to realize one can create the arbitrary number of the TPads at the arbitrary locations of the TCanvas.  

   TCanvas *c1 = new TCanvas("c1","The Ntuple canvas",200,10,700,780);
   TPad *pad1 = new TPad("pad1","This is pad1",0.02,0.52,0.48,0.98,21);
   TPad *pad2 = new TPad("pad2","This is pad2",0.52,0.52,0.98,0.98,21);
   TPad *pad3 = new TPad("pad3","This is pad3",0.02,0.02,0.48,0.48,21);
   TPad *pad4 = new TPad("pad4","This is pad4",0.52,0.02,0.98,0.48,1);
   pad1->Draw();
   pad2->Draw();

   pad3->Draw();
   pad4->Draw();

In your case:

   TCanvas *c1 = new TCanvas("c1","The Ntuple canvas",200,10,700,780);

   TPad *pad1 = new TPad("A","This is \"A\"",  0.0,    1./4,       1.,      1.  );
   TPad *pad2 = new TPad("a", "This is \"a\"",   0.0,    0.0,      1./4,   1./4 );
   TPad *pad3 = new TPad("b", "This is \"b\"",  1./4     0.0,      1.0,    1./4 );
 

Hope this helps, Valeri

+-++---+

  a b

A:B = 3:1
