Description

The Std Graph Analysis Smooth Savitzky command performs a smoothing of the selected curve using the Savitzky-Golay method.

Usage

  1. Select the Analysis → Smooth → Savitzky Golay... option from the menu.

Note

This command performs a smoothing of the selected curve using the Savitzky-Golay method. The formula used to smooth the curve defined by the points yi=f(xi) is:

The data consists of a set of points {xj, yj}, j = 1, ..., n, where xj is an independent [math]\displaystyle{ Y_j= \sum _{i=\tfrac{1-m}2}^{\tfrac{m-1}2}C_i\, y_{j+i},\qquad \frac{m+1}{2} \le j \le n-\frac{m-1}{2} }[/math]
