Plots may be displayed in one of five styles: lines, points,
linespoints, impulses, or dots. The lines style connects
adjacent points with lines. The points style displays a small
symbol at each point. The linespoints style does both lines and
points. The impulses style displays a vertical line from the X
axis to each point. The dots style plots a tiny dot at each data
point; this is useful for scatter plots with many points.
Default styles are chosen with the set function style and set
data style commands. See plot style for information about how
to override the default plotting style for individual functions.
Syntax:
set function style <style>
set data style <style>

Where <style> is either lines, points, linespoints, impulses,
or dots.
