It is also possible to visualize partial errors (from a subset of the parameters),
as shown above.


<h4>Binned dataset generation</h4>

A new method <tt>RooAbsPdf::generateBinned()</tt> has been implemented
that samples binned datasets (<tt>RooDataHist</tt>) from any
p.d.f.
<pre>
   RooDataHist* data = pdf.generateBinned(x,10000) ;
</pre>
This binned generation interface samples the p.d.f. at each bin
center and applies a Poisson fluctuation to each
