• ColorFunctionScaling is an option for graphics functions which specifies whether arguments supplied to a color function should be scaled to lie between 0 and 1.
• The usual default setting is ColorFunctionScaling -> True.
• With ColorFunctionScaling -> False original unscaled values are fed to the color function.
• Scaling is done so as to make the minimum and maximum values displayed with the current setting for PlotRange
be 0 and 1.
• New in Version 4.
