        [GREG1\]HISTOGRAM  [Array_X Array_Y] [/BASE [Ybase]] [/BLANKING Bval
    Eval] [/FILL [Icolor]] [/HATCH [Ipen] [Angle] [Separ] [Phase]]

    Connects the coordinates read by COLUMN X and Y, or stored in the  vari-
    ables  Array_X  Array_Y  as  a  histogram.  The /BASE option specifies a
    "true" histogram, connected to  a  base  level  (Default  Ybase=0).  The
    /BLANKING  option will supersede the current blanking values (as defined
    by SET BLANKING command) so that data points with  abs(Y(i)-Bval) < Eval
    are not plotted. Eval negative means no blanking value. Filled Histogram
    is created by the options /FILL + /BASE.
