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