NAME

6       DPVECT - Specifies the second and following points in a sequence of
7       points, in the user coordinate system, defining a curve to be drawn.
8

SYNOPSIS

10       CALL DPVECT (XCPU,YCPU)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       void c_dpvect (float xcpu, float ycpu);
16

DESCRIPTION

18       XCPU        (an input expression of type REAL) specifies the X
19                   coordinate of a point, in the user coordinate system.
20
21       YCPU        (an input expression of type REAL) specifies the Y
22                   coordinate of a point, in the user coordinate system.
23

C-BINDING DESCRIPTION

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

USAGE

29       Call DPFRST to do a "pen-up" move to the first of a sequence of points
30       defining a curve.  Call DPVECT to do "pen-down" moves to each of the
31       other points in the sequence and then call DPLAST to finish drawing the
32       curve and flush the buffers.
33
34       DPVECT maps the input coordinates to the fractional coordinate system
35       and then does a "pen-down" call to either DPDRAW (if smoothing is
36       turned off) or to DPSMTH (if smoothing is turned on) with those
37       coordinates.
38

EXAMPLES

40       Use the ncargex command to see the following relevant examples: tdshpk.
41

ACCESS

43       To use DPVECT or c_dpvect, load the NCAR Graphics libraries ncarg,
44       ncarg_gks, and ncarg_c, preferably in that order.
