VectorColorFunction

VectorColorFunction
is an option for VectorPlot and related functions which specifies a function to apply to determine colors of field vectors drawn.

MORE INFORMATION

The setting for VectorColorFunction is applied to the coordinates associated with the center of each field vector to determine the color to use to render the field vector.

With the setting VectorColorFunction->func, the arguments supplied to func are as follows:

	VectorPlot,ListVectorPlot, StreamPlot,ListStreamPlot, LineIntegralConvolutionPlot, ListLineIntegralConvolutionPlot	x, y, , , Norm
	VectorDensityPlot, ListVectorDensityPlot,StreamDensityPlot, ListStreamDensityPlot	x, y, , , s
	VectorPlot3D,ListVectorPlot3D	x, y, z ,, , , Norm

With the usual default setting VectorColorFunctionScaling->True, the arguments supplied to func are scaled to lie in the range 0 to 1.

With VectorColorFunctionScaling->False original unscaled values are used.

VectorColorFunction is equivalent to VectorColorFunction where the slot used is as follows: VectorPlot, ListVectorPlot, etc.: (Norm), VectorDensityPlot, ListVectorDensityPlot, etc.: (s), VectorPlot3D and ListVectorPlot3D: (Norm).

The list of possible color function names is given by ColorData.

The function specified by VectorColorFunction must return color directives such as RGBColor and Hue or named colors such as Red and Blue.

It can also return Opacity, as well as Glow and Specularity.

Combinations of directives can be specified using Directive.
