Specifies the input XY data range to be smoothed.
Note: From Origin 2024, it supports to smooth multiple datasets in the same Worksheet at one processing, for example XYYY and XYXYXY data columns.
See Specifying Your Input Data.
Specifies the smoothing method to be used. The default is Savitzky-Golay.
When Method is Adjacent-Averaging, check this box to use weighted averaging.
When Method is either Lowess or Loess, you can specify span by these three options:
When Points of Window is selected for Specify Span by, specifies the number of points in the moving window. Otherwise, you can use this parameter to control the cutoff frequency for the FFT filter. Larger values produce greater smoothing. Must be a non-zero positive value. See the algorithm section for the computation of cutoff frequency.
When Proportion is selected for Specify Span by, controls the proportion value for the span. Larger values produce greater smoothing.
When X Value is selected for Specify Span by, specifies the X Value. By default, this X Value is 0.1*(x max-x min).
Not available when Method is FFT Filter/Lowess/Loess.
Available when Method is Savitzky-Golay.
Controls the percentile to be used in percentile filtering. The default is 50%, which corresponds to replacing the signal point with median value of the data points in the data window. Available only when Method is Percentile Filter.
Read-only box showing the cutoff frequency of the low-pass filter. This parameter is visible only when Method is FFT Filter or Binomial.
Sampling interval. Clear Auto checkbox to set Sample Interval manually. Only available when Method is Binomial.
Default value is 1. Clear the Auto checkbox to set Order manually. Only available when Method is Binomial.
Determine where to output the smoothed signal. See Output Results.
