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

        Connect  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  lev-
        el.  A  scalar  value means a flat base level, while a 1D variable (same
        size as X and Y arrays) means a custom base for each bin. Default  is  0
        base level.

        The  /BLANKING option will supersede the current blanking values (as de-
        fined   by   SET BLANKING   command)   so   that   data   points    with
        abs(Y(i)-Bval) < Eval  are  not plotted. Eval negative means no blanking
        value. Blanking always applies on bin counts, i.e.  Array_Y  values,  or
        Array_X values if /Y is present.

        By  default,  binning  is done along X axis (assuming increasing Array_X
        values), and Array_Y provides the  bin  counts.  This  can  be  reverted
        thanks to option /Y. In this case, binning is one along Y axis (assuming
        increasing Array_Y values), and Array_X provides the  bin  counts.  This
        creates a 90 degrees rotated histogram.
