NAME

       CURVED - Draws a curve through a sequence of points.

SYNOPSIS

       CALL CURVED (X,Y,N)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_curved (float *x, float *y, int n)

DESCRIPTION

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

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

       N           (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 description.

USAGE

       The statement

             CALL CURVED (X,Y,N)

       is equivalent to the statements

             CALL FRSTD (X(1),Y(1))
             CALL VECTD (X(2),Y(2))
             CALL VECTD (X(3),Y(3))
             ...(et cetera)...
             CALL VECTD (X(N),Y(N))
             CALL LASTD

       The  basic  difference  is  that  CURVED  requires  you to have all of the coordinates defining the curve
       available at once; sometimes this is convenient and sometimes it is not.

       If three or more distinct points are given, and if one of the smoothing versions  of  Dashline  is  being
       used,  and if the internal parameter that suppresses smoothing is not set, then splines under tension are
       used to generate a smooth curve; the number of points actually used to draw the curve will depend on  its
       length.   In all other cases, the "curve" will be approximated by just connecting the given points in the
       specified order.

ACCESS

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

       See  the  man  page  for  dashline  to  see  how to access the quick, normal, smooth, and super line draw
       options.
