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.


#include <ncarg/ncargC.h>

void c_vector (float px, float py)

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

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

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

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.

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

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

frstpt, line, curve, ncarg_cbind
