This technique shows the code segment for a curve that can exhibit a concave curve on the first (upper) part of the range in a downward arc and a convex curve on the lower part of the range continuing downward. This is one of several complex curves that allow different shapes to be created by using input variables that can tune the shape of the curve.
With this curve the Top Config (Start of Curve) (index 1) and the Bottom Config (index 2) can be set with input variables. When configuring these values to precise values using the Auto Tuning function, set the Top Setup INPUT (index 1) first with the INPUT set to 0, then set the Bottom Setup INPUT (index 2) with the INPUT set to 100. The midpoint of the curve can be shifted left and right with index 3 and shifted up and down with index 4.
