Detailed Description

the same mapping as in the base class. However the automatic scaling is done using the average of the absolute values of the provided numbers. The average of the absolute values is multiplied by the factor to give the range.

void CColorScaleAverage::passValue ( const C_FLOAT64 & )

virtual

with this method numbers are passed to the automatic scaling algorithm.
