Custom Polyline GraphMapper. How?

Dear Grasshoppers.

I'd like to use a polyline as a GraphMapper curve, like this:

I would like to check the Y value of the polyline at regular X-intervals.

 

I could create a bunch of lines and intersect them with the polyline to get points, but is there a more "mathematical" way? Evaluate curve wouldn't work because then it wouldn't be even steps along the X-axes.

Any ideas?

Thanks!

It seems like there should be a better way to get real-time interactivity, but I'm not sure how...

 

Maybe Luis and the Howl or Firefly groups would have some ideas?
