NAME

       CURVE - draws the curve defined by a specified series of points in the user coordinate
       system.  The "pen" (for subsequent calls to FRSTPT, VECTOR, PLOTIF, and PLOTIT) is left at
       the location of the last point in the curve.

SYNOPSIS

       CALL CURVE (PX,PY,NP)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_curve (float *px, float *py, int np)

DESCRIPTION

       PX          (an input array of type REAL) defines the X user coordinates of the curve.
                   Array PX is of length NP.

       PY          (an input array of type REAL) defines the Y user coordinates of the curve.
                   Array PY is of length NP.

       NP          (an input expression of type INTEGER) specifies the number of points in the
                   curve.

C-BINDING DESCRIPTION

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

USAGE

       If the routine SET was not called, or if it was called with a linear mapping in both the X
       and Y coordinates, then the GKS routine GPL is called to output a polyline of length NP
       points.  If the mapping in either axis is logarithmic, the input coordinates are
       transformed and drawn ten points at a time. (The last segment may be less than ten
       points.)

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

EXAMPLES

       Use the ncargex command to see the following relevant examples: sfex01, sfex02, and
       tsoftf.

ACCESS

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