PLOT

            LAS\PLOT [ArrayName] [/INDEX] [/OBS]

        PLOT /OBS
            Display  the Observation in R. 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. It is equivalent to the
            following sequence of commands:
                CLEAR DIRECTORY  ! i.e. clear only the current window
                BOX
                SPECTRUM [ArrayName]
                TITLE
            The type of PLOT can be specified by SET PLOT. The limits for the  X
            and Y axes are set by SET MODE X and SET MODE Y.

        PLOT /INDEX
            Equivalent to the following sequence of commands:
                CLEAR DIRECTORY
                BOX /INDEX
                SPECTRUM /INDEX
                TITLE /INDEX
            Plot a 2-dimensional image (built with the LOAD command) with veloc-
            ity/frequency for the X axis, index number for the Y-axis,  and  in-
            tensity being rendered as grey/color scale. Use SET MODE Y to choose
            the color lower and upper limits. Entering command POPUP after  PLOT
            /INDEX  enables  displaying  a single spectrum, selected by clicking
            with the middle button of the mouse. Use SET MODE Z to  control  the
            second dimension of the plot (e.g. number of entries).

        Default is /OBS. The default can be modified with SET ACTION.
