NAME

       VECTOR - generates a "pen-down" move to a specified point in the user coordinate system.  VECTOR is used
       in conjunction with the routine FRSTPT to draw lines.

SYNOPSIS

       CALL VECTOR (PX,PY)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_vector (float px, float py)

DESCRIPTION

       PX          (an input expression of type REAL) defines the X user coordinate.

       PY          (an input expression of type REAL) defines the Y user coordinate.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       Polyline  type,  line  width,  and  color  can be set by calling the GKS routines GSLN, GSLWSC, GSCR, and
       GSPLCI before calling VECTOR.

       Note that, for the sake of efficiency, the routines FRSTPT and VECTOR buffer the polylines resulting from
       pen moves.  One must be sure to flush the SPPS polyline buffer before changing  polyline  attributes.   A
       "CALL PLOTIF (0.,0.,2)" will flush the buffer.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tgflas.

ACCESS

       To  use VECTOR or c_vector, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.
