NAME
gpl - Draw line segments connecting a sequence of user-specified coordinate pairs
SYNOPSIS
CALL GPL (N, X, Y)
C-BINDING SYNOPSIS
#include <ncarg/gks.h>
void gpolyline(const Gpoint_list *point_list);
DESCRIPTION
This output primitive draws line segments connecting a sequence of user-specified coordinate pairs.
|
N |
(Integer, Input) - The number of points in the line to be drawn. N must be larger than one. | ||
|
X (N) |
(Real Array, Input) - The X coordinates (specified in world coordinates) of the N points to be connected by line segments. | ||
|
Y (N) |
(Real Array, Input) - The Y coordinates (specified in world coordinates) of the N points to be connected by line segments. |
USAGE
Note that the coordinate pairs must be in world coordinates and not user coordinates. Among other things, this means that the log scaling and mirror-imaging features available via the SET call and the SPPS functions for drawing lines are not applicable here.
ACCESS
To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
