NAME

6       VECTOR - generates a "pen-down" move to a specified point in the user
7       coordinate system.  VECTOR is used in conjunction with the routine
8       FRSTPT to draw lines.
9

SYNOPSIS

11       CALL VECTOR (PX,PY)
12

C-BINDING SYNOPSIS

14       #include <ncarg/ncargC.h>
15
16       void c_vector (float px, float py)
17

DESCRIPTION

19       PX          (an input expression of type REAL) defines the X user
20                   coordinate.
21
22       PY          (an input expression of type REAL) defines the Y user
23                   coordinate.
24

C-BINDING DESCRIPTION

26       The C-binding argument descriptions are the same as the FORTRAN
27       argument descriptions.
28

USAGE

30       Polyline type, line width, and color can be set by calling the GKS
31       routines GSLN, GSLWSC, GSCR, and GSPLCI before calling VECTOR.
32
33       Note that, for the sake of efficiency, the routines FRSTPT and VECTOR
34       buffer the polylines resulting from pen moves.  One must be sure to
35       flush the SPPS polyline buffer before changing polyline attributes.  A
36       "CALL PLOTIF (0.,0.,2)" will flush the buffer.
37

EXAMPLES

39       Use the ncargex command to see the following relevant examples: tgflas.
40

ACCESS

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