Graphing

I feel as though this should be a really easy answer and I am just looking over it. I am importing live values (XYZ) from a program (OPTI track- unimportant) into MAX 6. I have already figured out how to determine the aceleration, velocity and frequency with in the program. My goal how ever is how to graph these numbers in real time into a graph wile saving the data to an exportable txt document. If i can get it to graph, and record? the data I wouldn't necessarily need the .txt. but it would be nice. I can seem to find a streaming way to do this. Any and all help would be fantastic! thanks!
