13
14 void c_wmbarb(float x, float y, float u, float v)
15
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
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
37 To use WMBARB or c_wmbarb, load the NCAR Graphics libraries ncarg,
38 ncarg_gks, and ncarg_c, preferably in that order.
