6. LINE TYPE:


   This option allows you to choose the style of line used to
represent each curve being plotted.  You may select from a solid
line, a dot, a dot-dash, a short dot-dash, and a long dot dash.
You may wish to choose this option if simultaneous curves are
being plotted, as they may be distinguished by different line
types.  The default value is a solid line.  The line type is
unspecifiable if in option 3, 'Specify Plot Type', the points
option has been chosen.
