Did you get an answer to this? I too need to find this method.

Hello Wise Ones
I am considering adding a control to allow users to use a Bezier Path
to edit a set of values that change over time. The essentials are a
timeline with values determined by keyframes which will be represented
by Bezier nodes.
My question is, is there a simple way to derive the y value of a
bezier line segment given an x coordinate. Assume that there is no
circumstance where more than one y value might exist for a given x
value. I don't see anything in the NSBezierPath documentation that
indicates that this is supported.
For the purposes I will be putting this to, a close approximation - eg
2% error - would suffice.
Anyone?
