SYNOPSIS

#include <ncarg/gks.h>

void gpolymarker(const Gpoint_list *point_list);

DESCRIPTION

The polymarker output primitive draws selected symmetric symbols to mark user-specified coordinate positions.

point_list.num_points

(Gint, Input) - The number of markers to be drawn. Must be greater than zero.

point_list.points

(Gpoint *, Input) - The X and Y coordinates of the point_list.num_points markers to be drawn, in world coordinates.

USAGE

By default, the polymarker type is an asterisk. To select other polymarker types and attributes, see the man page for gset_marker_type(3NCARG).

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 c_set call and the SPPS functions for drawing dots and markers are not applicable here.

ACCESS

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