       A transformation using pow()

       QwtPowerTransform preserves the sign of a value. F.e. a transformation with a factor of 2 transforms a
       value of -3 to -9 and v.v. Thus QwtPowerTransform can be used for scales including negative values.

QwtTransform*QwtPowerTransform::copy()const[virtual]Returns:
           Clone of the transformation

       Implements QwtTransform.

   doubleQwtPowerTransform::invTransform(doublevalue)const[virtual]Parameters:value Value to be transformed

       Returns:
           Inverse exponentiation preserving the sign

       Implements QwtTransform.

   doubleQwtPowerTransform::transform(doublevalue)const[virtual]Parameters:value Value to be transformed

       Returns:
           Exponentiation preserving the sign

       Implements QwtTransform.
