Default Curve fitting algorithm

Hi

I have recently been impressed with the fitting of lines to many thousands
of data points in Excel when displaying this information on a chart, and am
wondering if anyone knows the algorithm that is used to make decisions about
the types of curves (e.g. simple polynomials, splines, Bezier...) used with a
particular data set?

Thanks

Ringo
