That applet is also computing the points at the resolution of the
screen. I doubt that would be possible in your situation.
I agree with Chris in don't think of it as a line. Think of it as a
series of points. I'd also suggest to think of it as a curve. Curve
Fitting Algorithms do a decent job forecasting a path based upon a
series of sample points.
NIST has an excellent list of links to all kinds of Numerical Methods.
