COLUMN

        [GREG1\]COLUMN [X Nx] [Y Ny] [Z Nz] [/FILE File_Name] [/LINES L1 L2]
    [/TABLE Table_Name]

    This command will read X data from column Nx of the current file, Y data
    from  column  Ny and Z data from column Nz of the current (or specified)
    input file or binary table. Any combination of any of three X,Y,Z  items
    is  valid  in  any order, provided the column number immediately follows
    the column descriptor. The X and Y arrays contain respectively the X and
    Y  coordinates  of  points  to  be plotted. The Z array is an additional
    buffer which is used for ERRORBARS, for RANDOM maps and so on.
