15 point_list.num_points
16 (Gint, Input) - The number of points in the line to be
17 drawn. Must be larger than one.

19 point_list.points
20 (Gint *, Input) - The X and Y coordinates (specified in
21 world coordinates) of the point_list.num_points points to
22 be connected by line segments.

25 Note that the coordinate pairs must be in world coordinates and not
26 user coordinates. Among other things, this means that the log scaling
27 and mirror-imaging features available via the c_set call and the SPPS
28 functions for drawing lines are not applicable here.

31 To use the GKS C-binding routines, load the ncarg_gks and ncarg_c
32 libraries.
