NAME

       WMBARB - plots wind barbs.

SYNOPSIS

       CALL WMBARB (X,Y,U,V)

C-BINDING SYNOPSIS

       #include <ncarg/gks.h>

       void c_wmbarb(float x, float y, float u, float v)

DESCRIPTION

       X           (Real,  Input)  -  An X coordinate (specified in world coordinates) of a point
                   that specifies the position of the base of a wind barb.

       Y           (Real, Input) - A Y coordinate (specified in world  coordinates)  of  a  point
                   that specifies the position of the base of a wind barb.

       U           (Real, Input) - The X component of a wind vector.

       V           (Real, Input) - The Y component of a wind vector.

USAGE

       The  angle  at  which  the  wind  barb  is drawn is determined by the vector (U,V) and the
       magnitude of that vector denotes the  wind  speed  in  knots.   Set  the  values  for  the
       appropriate  internal  parameters  before  calling  WMBARB  to produce the wind barb.  The
       internal parameters that control the appearance of wind barbs are:  COL,  WBA,  WBD,  WBF,
       WBS, WBT.

ACCESS

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