VECTOR(3NCARG)                   NCAR GRAPHICS                  VECTOR(3NCARG)



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.
