[ROOT] TGAxis drawing problem

dear rooters,
I am trying to draw an additional axis to an existing hisotgram, following
the example given in the tutorials.
I cut and pasted the code and put it into my executable, that links the
libraries from:

/afs/cern.ch/sw/root/v3.05.07/rh73_gcc296/root

I don't have any problems in compiling nor running the code, but, even if
I put in the code:

  TGaxis axis(gPad->GetUxmax(), gPad->GetUymin(),
          gPad->GetUxmax(),
  gPad->GetUymax(),0,extremes[sensIndex->second][1],510,"+R");
  axis.SetLineColor(1);
  axis.SetTextColor(1);
  axis.Draw();

the additional axis is not drawn in the pad.
If I remove all the plots before the axis's one, then the axis alone is
plotted without any problem.

Is there anything that I am missing?

Thank you very much

pietro
