 Drawing options
  chopt='L' :  A simple polyline between every points is drawn
  chopt='F' :  A fill area is drawn ('CF' draw a smooth fill area)
  chopt='A' :  Axis are drawn around the graph
  chopt='C' :  A smooth Curve is drawn
  chopt='*' :  A Star is plotted at each point
  chopt='P' :  Idem with the current marker
  chopt='B' :  A Bar chart is drawn at each point
  chopt='1' :  ylow=rwymin
  chopt='X+' : The X-axis is drawn on the top side of the plot.
  chopt='Y+' : The Y-axis is drawn on the right side of the plot.

    Fitting options
   The list of fit options is given in parameter option.
      option = "W"  Set all errors to 1
             = "U" Use a User specified fitting algorithm (via SetFCN)
             = "Q" Quiet mode (minimum printing)
             = "V" Verbose mode (default is between Q and V)
             = "B" Use this option when you want to fix one or more parameters
                   and the fitting function is like "gaus","expo","poln","landau".
             = "R" Use the Range specified in the function range
             = "N" Do not store the graphics function, do not draw
             = "0" Do not plot the result of the fit. By default the fitted function
                   is drawn unless the option"N" above is specified.
             = "+" Add this new fitted function to the list of fitted functions
                   (by default, any previous function is deleted)
             = "C" In case of linear fitting, not calculate the chisquare
                    (saves time)
             = "F" If fitting a polN, switch to minuit fitter
             = "ROB" In case of linear fitting, compute the LTS regression
                     coefficients (robust(resistant) regression), using
                     the default fraction of good points
               "ROB=0.x" - compute the LTS regression coefficients, using
                           0.x as a fraction of good points

 Fit by gaus where first parameter is the number of events under ga
 Oct 15, 2007

 You can change parameters after that if you don't like this assumption

 Fit by gaus where first parameter is the number of events under ga

 First parameter is integral (number events under gaus)
 Forth parameter (par[3]) is width of histogram bin
 gaus(0) is a substitute for [0]*exp(-0.5*((x-[1])/[2])**2)

 First parameter is integral (number events under gaus)
 Forth parameter (par[3]) is width of histogram bin
 gaus(0) is a substitute for [0]*exp(-0.5*((x-[1])/[2])**2)
 + pol2 -> 7 parameters
