The labels style can also be used in 3D plots. In this case four input column specifiers are required,
corresponding to X Y Z and text.

36 Lines
The lines style connects adjacent points with
straight line segments. It may be used in either
2D or 3D plots. The basic form requires 1, 2, or
3 columns of input data. Additional input columns
may be used to provide information such as variable
line color (see rgbcolor variable (p. 33)).
2D form
1 column: y # implicit x from row number
2 columns: x y
with lines
3D form
1 column: z # implicit x from row, y from index
3 columns: x y z

37 Linespoints
The linespoints style does both lines and points,
that is, it draws a small symbol at each point and
then connects adjacent points with straight line segments.
The command set pointsize may be used
to change the size of the points. See set pointsize
(p. 126) for its usage. 1 or 2 columns of basic input
data are required in 2D plots; 1 or 3 columns
are required if 3D plots. See style lines (p. 49).
Additional input columns may be used to provide
information such as variable point size or line color.
linespoints may be abbreviated lp.

38 Points
The points style displays a small symbol at each
point. The command set pointsize may be used to
change the default size of the points. 1 or 2 columns
of basic input data are required in 2D plots; 1 or 3
columns are required if 3D plots. See style lines
(p. 49). Additional input columns may be used to
provide information such as variable point size or
line color.
