You are asking for curve-fitting. There is a HUGE amount of work on curve-fitting in computer science and statistics. Generally, you start with some data points (x, y). You generally have some idea of what sort of function you expect -- is it a straight line? A curve? What sort of curve? A polynomial, an exponential, a sine curve, a cubic spline, a Bezier curve? You might like to google on "least squares curve fitting" and "linear regression". That's just two methods out of many. Some curve-fitting methods also estimate the error between the predicted curve and the data points; you could then try all of the methods and pick the one with the least error. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
