Description:

            SUBROUTINE PGBIN (NBIN, X, DATA, CENTER)
            INTEGER NBIN
            REAL X(*), DATA(*)
            LOGICAL CENTER
      
       Plot a histogram of NBIN values with X(1..NBIN) values along
       the ordinate, and DATA(1...NBIN) along the abscissa. Bin width is
       spacing between X values.
      
       Arguments:
        NBIN   (input)  : number of values.
        X      (input)  : abscissae of bins.
        DATA   (input)  : data values of bins.
        CENTER (input)  : if .TRUE., the X values denote the center of the
                          bin; if .FALSE., the X values denote the lower
                          edge (in X) of the bin.
