NAME

6       GPL (Polyline) - This output primitive draws line segments connecting a
7       sequence of user-specified coordinate pairs.
8

SYNOPSIS

10       CALL GPL (N, X, Y)
11

C-BINDING SYNOPSIS

13       #include <ncarg/gks.h>
14
15       void gpolyline(const Gpoint_list *point_list);
16

DESCRIPTION

18       N           (Integer, Input) - The number of points in the line  to  be
19                   drawn. N must be larger than one.
20
21       X (N)       (Real Array, Input) - The X coordinates (specified in world
22                   coordinates) of the N points to be connected by  line  seg‐
23                   ments.
24
25       Y (N)       (Real Array, Input) - The Y coordinates (specified in world
26                   coordinates) of the N points to be connected by  line  seg‐
27                   ments.
28

USAGE

30       Note  that  the  coordinate  pairs must be in world coordinates and not
31       user coordinates.  Among other things, this means that the log  scaling
32       and  mirror-imaging  features  available  via the SET call and the SPPS
33       functions for drawing lines are not applicable here.
34

ACCESS

36       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
