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.
