Visual graph

Hello,

I'm writing this musical composition, in which I've taken a tide graph of a city and want to turn it into a patch. I was thinking of using the function object or maybe a table or itable (this last one apparently is not applicable since it gives weighted probabilities). The point of the function object would be to "paint" the tide graph in the object itself and somehow make it trigger musical events, like density or octave jumps and etc. (haven't really gotten there yet haha). The function object would rely on a master timer I've got setup, which just goes from 0 to 100. Any ideas what I can use to execute this compositional idea? Help is appreciated!
