                 legend=   plotting keyword

         sets the legend for a plot.  The default legend is a concatentation
         of the strings used in the original plotting command (plg, plm, etc.),
         except for the plt command, which has no default legend.
         Legends are never plotted to the X window; use the plq command to
         see them interactively.  Legends will appear in hardcopy output
         unless they have been explicitly turned off.

                 limits
              or limits, xmin, xmax, ymin, ymax,

    	            square=0/1, nice=0/1, restrict=0/1
    	 or old_limits= limits()
    	 or limits, old_limits
         In the first form, restores all four plot limits to extreme values.
         In the second form, sets the plot limits in the current coordinate
         system to XMIN, XMAX, YMIN, YMAX, which may be nil or omitted to
         leave the corresponding limit unchanged, a number to fix the
         corresponding limit to a specified value, or the string "e" to
         make the corresponding limit take on the extreme value of the
         currently displayed data.
         If present, the square keyword determines whether limits marked
         as extreme values will be adjusted to force the x and y scales
         to be equal (square=1) or not (square=0, the default).
         If present, the nice keyword determines whether limits will be
         adjusted to nice values (nice=1) or not (nice=0, the default).
         There is a subtlety in the meaning of "extreme value" when one
         or both of the limits on the OPPOSITE axis have fixed values --
         does the "extreme value" of the data include points which
         will not be plotted because their other coordinate lies outside
         the fixed limit on the opposite axis (restrict=0, the default),
         or not (restrict=1)?
         If called as a function, limits returns an array of 5 doubles;
         OLD_LIMITS(1:4) are the current xmin, xmax, ymin, and ymax,
         and int(OLD_LIMITS(5)) is a set of flags indicating extreme
         values and the square, nice, restrict, and log flags.
         In the fourth form, OLD_LIMITS is as returned by a previous
         limits call, to restore the limits to a previous state.
         In an X window, the limits may also be adjusted interactively
         with the mouse.  Drag left to zoom in and pan (click left to zoom
         in on a point without moving it), drag middle to pan, and click
         (and drag) right to zoom out (and pan).  If you click just above
         or below the plot, these operations will be restricted to the
         x-axis; if you click just to the left or right, the operations
         are restricted to the y-axis.  A shift-left click, drag, and
         release will expand the box you dragged over to fill the plot
         (other popular software zooms with this paradigm).  If the
         rubber band box is not visible with shift-left zooming, try
         shift-middle or shift-right for alternate XOR masks.  Such
         mouse-set limits are equivalent to a limits command specifying
         all four limits EXCEPT that the unzoom command can revert to
         the limits before a series of mouse zooms and pans.
         The limits you set using the limits or range functions carry over
         to the next plot -- that is, an fma operation does NOT reset the
         limits to extreme values.

                 logxy, xflag, yflag

         sets the linear/log axis scaling flags for the current coordinate
         system.  XFLAG and YFLAG may be nil or omitted to leave the
         corresponding axis scaling unchanged, 0 to select linear scaling,
         or 1 to select log scaling.
