    It depends on how you intend to match graphs, by values or by shape?
    Are the graphs as line graphs or what?
    Need more info please.

    Hi, I don't know if it will help you in some way, but if you have some little mathematics knowledge you can read something about CORRELATION. It's a math algorithm yo match functions, signals or whatever. The key is that you can use a 2D correlation to match your graphs, it's very accurate and fast.
    If you are interested in this write me a mail (SigmaOrion@gmail.com) and I'll help you.
    Good luck...
