Class Description

                                                                      
 VNtuplePlayer                                                        
                                                                      
 A VNtuple is an ntuple containing slow monitoring data               
 The player will allow one to draw some plots related to this         
 VNtuple.                                                             
 The vntuple player is loaded only when needed by the system, it is   
 not linked at compile time with the program

*-*                  ===========================================

 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(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.
