    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 buf-
    fer which is used for ERRORBARS, for RANDOM maps and so on.
