Scale

Value scaling

It is possible to specify a linear transformation of the value acquired from the variable. The following options are available:

  • None: the acquired value is used as is
  • Proportional: the acquired value is multiplied by a scale factor
  • Linear interpolation: the acquired value is transformed through a linear interpolation function defined by multiple points

For each variable value (column Input), it is possible to specify the corresponding value after scaling (column Output). It is possible to add and remove points (at least two are necessary).

It is possible to specify what to do for values outside the specified range:

  • Clamp: values outside the range are brought to the specified minimum or maximum value
  • Extrapolate: values outside the range are calculated through the equation of the line defined by the two closest points
  • Ignore: values outside the range are considered null
