This icon combines scalar fields for the purpose of plotting as a vector pair. The user supplies GRIB data of vector X and Y components (cartesian coordinates) or intensity/direction (polar coordinates) with the option of colouring the vectorial representation (arrows) according to the magnitude of a user supplied scalar quantity. The classic example is to plot a wind field from (U,V) components coloured according to Temperature. In order to apply a colour map, the Wind Plotting icon must be dropped into the plot.
The macro language equivalent is grib_vectors(). For an example, see Coloured Vectors Example.
