            LAS\SPECTRUM [ArrayName] [Yoff] [/INDEX] [/OBS] [/PEN Ipen]

        /OBS
            Plot the spectrum in the R buffer in the units and scales defined by
            SET UNIT and SET MODE. No argument or argument  "Y"  will  plot  the
            spectrum Y intensities of the R buffer (RY), but an associated array
            can be plotted instead given its name.

            Yoff (default 0) is a constant Y-offset added to the plotted  values
            (useful to compare two spectra).

            The option /PEN allows to use a i-th pen instead of the current one,
            without modifying it in return.

        /INDEX
            Plots the 2D array from the last LOAD command.

        Without option, the behavior depends on SET ACTION (see  PLOT).  Default
        is OBS.
