Class Description

                                                                      
 VNtuple                                                              
                                                                      
 A standard simple ntuple with some drawing options suitable for      
 GW analysis                                                          
                                                                      


Int_t DrawGraph(TCut varexp, TCut selection, Option_t *option, Int_t nentries, Int_t firstentry)
*-*-*-*-*-*-*-*-*-*-*Draw expression varexp for specified entries-*-*-*-*-*
*-*                  ===========================================

      This function accepts TCut objects as arguments.
      Useful to use the string operator +
         example:
            ntuple.Draw("x",cut1+cut2+cut3);


Int_t DrawGraph(const char *varexp0, const char *selection, Option_t *option,Int_t nentries, Int_t firstentry)
*-*-*-*-*-*-*-*-*-*-*Draw expression varexp for specified entries-*-*-*-*-*
*-*                  ===========================================

 This method differs from the "Draw" method in that it draws a graph of the
 selected variables, not a histogram. The options and comments are
 nevertheless the same and one should refer to TTree::Draw()
 This method should not be used for a graph that has more than approx 10^6
 points, because it fills quite rapidly the memory.
 The options available are the same as the ones in TGraph::Draw, except
 that a "T" option has been added, which sets the X axis to time mode
 display. This is only used in conjunction with the "A" mode.

Int_t DrawSeries(TCut varexp, TCut selection, Option_t *option, Int_t nentries, Int_t firstentry)
*-*-*-*-*-*-*-*-*-*-*Draw expression varexp for specified entries-*-*-*-*-*
*-*                  ===========================================

      This function accepts TCut objects as arguments.
      Useful to use the string operator +
         example:
            ntuple.DrawSeries("x",cut1+cut2+cut3);


Int_t DrawSeries(const char *varexp0, const char *selection, Option_t *option,Int_t nentries, Int_t firstentry)
*-*-*-*-*-*-*-*-*-*-*Draw expression varexp for specified entries-*-*-*-*-*
*-*                  ===========================================

 This method differs from the "Draw" method in that it draws a  time series
 graph of the selected variable, not a histogram.
 The options and comments are nevertheless the same and one should refer
 to TTree::Draw()
 This method should not be used for a series that has more than approx 10^6
 points, because it fills quite rapidly the memory.
 The options available are the same as the ones in VSPlot::Draw.

VVirtualNtuplePlayer* GetPlayer()
