NAME

6       gpolyline  (Polyline)  - This output primitive draws line segments con‐
7       necting a sequence of user-specified coordinate pairs.

SYNOPSIS

10       #include <ncarg/gks.h>
11
12       void gpolyline(const Gpoint_list *point_list);

DESCRIPTION

15       point_list.num_points
16                   (Gint, Input) - The number of points  in  the  line  to  be
17                   drawn. Must be larger than one.
18
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.
23

USAGE

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.

ACCESS

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