ncl_gpl: This output primitive draws
NAMEGPL (Polyline) - This output primitive draws line segments connecting a sequence of user-specified coordinate pairs.
SYNOPSISCALL GPL (N, X, Y)
C-BINDING SYNOPSIS#include <ncarg/gks.h>
- (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.
USAGENote 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.
ACCESSTo use GKS routines, load the NCAR GKS-0A library ncarg_gks.
