Curve Math Operations - Step Function

Defines a step function that can be used to represent data of a step-type nature. The step function is very similar to the ramp function; the only difference being in the shape of the curve between minimum and maximum y values. See Plot for Step Function.
 
For the option:
Do the following:
X
Specifies the minimum and maximum values of the x-axis. For example, if we were creating a spring characteristic that ranged from -100 to 100 mm displacement, then we would use -100 as the minimum x value and 100 as the maximum x value.
Y
Specifies the minimum and maximum values of the y-axis. Continuing the example above, this would represent the force characteristics of the spring. For example, -1000 N as the minimum y value and 1000 N as the maximum y value.
Step
Specifies the starting and ending x values defining the point where the curve transitions from -y to +y. Continuing the examples above, you could use values of -75 (mm) and 75 (mm) representing the transition from minimum y to maximum y.
Points/Segs
Enter the points or intermediary segments for the curve.
