NAME
gpm - Polymarker output primitive to draw symmetric symbols
SYNOPSIS
CALL GPM (N, X, Y)
C-BINDING SYNOPSIS
#include <ncarg/gks.h>
void gpolymarker(const Gpoint_list *point_list);
DESCRIPTION
GPM (Polymarker) - the polymarker output primitive draws selected symmetric symbols to mark user-specified coordinate positions.
|
N |
(Integer, Input) - The number of markers to be drawn. N must be greater than zero. | ||
|
X (N) |
(Real Array, Input) - The X coordinates of the N markers to be drawn, in world coordinates. | ||
|
Y (N) |
(Real Array, Input) - The Y coordinates of the N 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 gsmk.
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 dots and markers are not applicable here.
ACCESS
To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
