Project vertical points from curve in waves not only in a linear direction

Hi! So i have a curve that i want to vertically project points from. My problem is that I can only project the curve in a linear direction, and i want to we able to have a graph or a slider so that i can project the curves in + and - vertical directions.

I can do it manually by copy and paste in rhino, but i figure there must be a easier way in grasshopper? Thank you in advance! Best, Siri !
