kitControl-Line
This component creates a linear output, which is based on an input signal, two support points (x1, y1) and (x2, y2), and optional input limiting. It calculates the output as follows: y = (m * in) + b, where m and b define the line intercepting the support points.

The properties Limit Below and Limit Above determine whether x1 and x2 are used to limit the input signal. If the limits are used, this component requires x1 < x2.
Properties:
Limit Below (defaults to true) - If true, limit input (in) must be no smaller than x1
- Limit Above (defaults to true) - If true, limit input (in) must be no smaller than x1
