Description:

Purpose
This app can be used to smooth 3D data from XYZ columns or a matrix. 
 

Installation
Download the file, then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window.
 

Operation

  1. Activate a worksheet with XYZ columns, or a matrix sheet with data.
  2. Click the icon in the Apps Gallery window to open the dialog.
  3. Select XYZ columns or matrix object as input.
  4. For XYZ data, the following smoothing methods are available:
    • Adjacent-Averaging
    • Adjacent-Median
    • Negative Exponential
    • Loess
    • Bisquare
    • Inverse Square
    For matrix data, two additional methods are available: FFT Filter, Convolution.
  5. Customize parameters for selected smoothing method.

    Note: For XYZ data, choose Fixed as Bandwidth Method if data points are relatively evenly spaced. Choose Nearest Neighbors if they are unevenly distributed.

  6. If you want to change output result's grid, you can enable Grid Settings and define maximum, minimum or grid size for X and Y ranges.
  7. Click Preview to view smoothed surface and raw data.
  8. Move the Azimuth/Inclination/Roll sliders to rotate preview graph.
  9. Uncheck Plot Raw Data to remove raw data plot from preview graph.
  10. Click OK to output the smoothed data.
