The Fortran name of this function is NhlFNDCPolymarker.
Given arrays containing the X and Y coordinates of points in NDC space, this function outputs an immediate-mode marker at each of the points.
#include <ncarg/hlu/hlu.h> #include <hfile for Transform class object> NhlErrorTypes NhlNDCPolymarker( int pid, int gsid, float *x, float *y, int n, )
subroutine NhlFNDCPolymarker(pid, gsid, x, y, n, ierr) integer pid, gsid, n, ierr float x(n), y(n)
Type name: NhlTErrorTypes Definition: typedef enum _NhlErrType{ NhlFATAL = -4, /* "FATAL" */ NhlWARNING = -3, /* "WARNING" */ NhlINFO = -2, /* "INFO" */ NhlNOERROR = -1 /* "NOERROR" */ } NhlErrorTypes;
You specify the polymarker's attributes by passing in a
GraphicStyle object using the parameter
gsid. If gsid is set to NhlNULLOBJID
(0) then the marker attributes are determined by the current settings
of the Workstation default
GraphicStyle object. Retrieve the id of the default
GraphicStyle object using the read-only
Workstation resource wkDefGraphicStyleId.
