Sample OPJ to download to try: LOWESS and LOESS Method.opj
LOWESS and LOESS smoothing options have been added to the Smooth tool.
Both methods are locally weighted scatterplot smoothing, the most significant advantage is that they capture the major trend of the data but will not be seriously influenced by the fluctuations of data in a small X range.
To use these methods, select Analysis: Signal Processing: Smooth from the Origin menu, when a worksheet or a graph is active.
And you can either use "Points of Window" to define the degree of smoothing (curve smoother with bigger points of window), or the proportion of span (curve smoother with bigger span).
