[ROOT] hstack->GetYaxis()->GetXmax()

Hello,

I do not succeed in getting the maximum of the Y axis of a THStack.

I have a table THStack* m_hstack[6];
I fill it (with several TH1F*), draw it, then I do:
  cout<<m_hstack[i]->GetYaxis()->GetXmax()<<endl;
and I get "1" (instead of about 50) !

Actually, when I do
  cout<<m_hstack[i]->GetYaxis()->GetNbins()<<endl;
I get "1" too (and also for GetBinWidth(1)).

For the X axis, I do not have this problem.

If it's the right method, have somebody an idea of my problem ?
Else, how can I get this maximum ?
Thank you.
