Updated Savitzky-Golay Smoothing Filter
The Savitzky-Golay Filter is a polynomial smoothing filter.
This version implements 3rd degree polynomials using coefficients from Savitzky and Golay's table, specifically the coefficients for a 5-, 7-, 9-, 15- and 25-point window moving averages.
The filters are offset to the left by the number of coefficients (n-1)/2 so it smooths on top of the actual curve.
You can turn off some of the smoothing curves, as it can get cluttered displaying all at once.
Any feedback is very welcome.

Release Notes
Savitzky-Golay digital filter, useful for smoothing data.This script implements the 5-, 7-, 9-, 15-, and 25-point window 3rd degree polynomial fit coefficients.
The plots are offset by (n-1)/2 where n is the window size, so it fits the original data.
Any feedback is welcome.
