x = the vertical position
y = the upper bound of the scale (e.g., 1-5 on a Likert scale or 1-10)
n = the number of vertical positions
z = the scale value of x
(x-1) (y-1)
(n-1) 		+ 1 = z
x =
y =
n =

= The scale value of x

The vertical position value must be higher than 0.
The upper bound value must be higher than 0.
