This App lets you create a 2D or 3D Vorinoi diagram from XY data or XYZ data.
For 2D Voronoi diagram, it outputs the area of each region; for 3D, volume.
Download the file Voronoi Diagram.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.
- Select XY/XYZ data in worksheet or active XY/XYZ data plot in graph.
- Click the Voronoi Diagram app icon.
For 2D voronoi diagram, you can specify a simple polygon as boundary by selecting 2 columns as XY.
- Click OK.
If started from worksheet, the app will create a Voronoi diagram automatically along with the input data as scatters. If started from graph, the graph will be updated accordingly.
The region Area/Volume is missing value if the region is infinite. To show the area/volume of a particular site in data info window, you can refer to the Region Area/Volume column. See Data Info Tool for details.
Region ID indicates the XY region for a particular site. To fill color to the regions, you can set the Fill Color by index of this column. Please refer to The (Plot Details) Pattern Tab for details.
