Method Detail

createScaler

Scaler createScaler(double lo,
                    double hi)

Returns a scaler instance that can scale input values in a given range. The given bounds define the range of input values that will be mapped to the fixed (0..1) output range. Input values outside that range will in general result in clipping, so for the returned scaler s:

    s.scaleValue(x) == s.scaleValue(lo) for x<lo
    s.scaleValue(x) == s.scaleValue(hi) for x>hi
 

Parameters:

lo - lower bound of unclipped input data value

hi - upper bound of unclipped input data value

Returns:
