C-BINDING SYNOPSIS

14       void c_wmbarb(float x, float y, float u, float v)
15

DESCRIPTION

17       X           (Real, Input) - An X coordinate (specified in world coordi‐
18                   nates) of a point that specifies the position of  the  base
19                   of a wind barb.
20
21       Y           (Real,  Input) - A Y coordinate (specified in world coordi‐
22                   nates) of a point that specifies the position of  the  base
23                   of a wind barb.
24
25       U           (Real, Input) - The X component of a wind vector.
26
27       V           (Real, Input) - The Y component of a wind vector.
28

USAGE

30       The  angle  at which the wind barb is drawn is determined by the vector
31       (U,V) and the magnitude of that vector denotes the wind speed in knots.
32       Set  the  values for the appropriate internal parameters before calling
33       WMBARB to produce the wind barb.  The internal parameters that  control
34       the appearance of wind barbs are: COL, WBA, WBD, WBF, WBS, WBT.
35

ACCESS

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