Are you sure you want an NSBezierPath to control a set of values? It
seems more like you want to have a lookup of values with smooth
interpolation, which could potentially be rendered using a
NSBezierPath. However, since you actually need to smoothly interpolate
values without the bezier path, it probably won't be necessary.
Cheers,

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?
