he simple following macro was enough to show the problem:
<pre>
   {
      TH1D h(&quot;h&quot;, &quot;h&quot;, 10., 0., 1.); h.Fill(.5);
      THStack s(&quot;s&quot;, &quot;s&quot;); s.Add(&amp;h);
      TCanvas canvas(&quot;canvas&quot;);
      frame = canvas.DrawFrame(-1., 0., 2., 2.);
      frame.SetLabelSize(0.05, &quot;XY&quot;);
      frame.Draw(); s.Draw(&quot;same&quot;);
   }
</pre>

<li> Make the data member <tt>fHistogram</tt> persistent in order to save the
     axis attributes which may
