  Data Members

    protected:

        TList* fGraphs     Pointer to list of TGraphs
         TH1F* fHistogram  Pointer to histogram used for drawing axis
      Double_t fMaximum    Maximum value for plotting along y
      Double_t fMinimum    Minimum value for plotting along y

Class Description

   A TMultiGraph is a collection of TGraph (or derived) objects
   Use TMultiGraph::Add to add a new graph to the list.
   The TMultiGraph owns the objects in the list.
   Drawing options are the same as for TGraph
   Example;
     TGraph *gr1 = new TGraph(...
     TGraphErrors *gr2 = new TGraphErrors(...
     TMultiGraph *mg = new TMultiGraph();
     mg->Add(gr1);
     mg->Add(gr2);
     mg->Draw("alp");

 TMultiGraph default constructor

 constructor with name and title

 TMultiGraph destructor

 add a new graph to the list of graphs

 Compute distance from point px,py to each graph

*-*-*-*-*-*-*-*-*-*-*Draw this multigraph with its current attributes*-*-*-*-*-*-*
*-*                  ==========================================

   Options to draw a graph are described in TGraph::PainGraph

    Returns a pointer to the histogram used to draw the axis
    Takes into account the two following cases.
       1- option 'A' was specified in TMultiGraph::Draw. Return fHistogram
       2- user had called TPad::DrawFrame. return pointer to hframe histogram

 Get x axis of the graph.

 Get y axis of the graph.

 paint all the graphs of this multigraph

 Print the list of graphs

 Save primitive as a C++ statement(s) on output stream out
