Voronoi Polygons for Spotfire® 1.1.0

2 Screenshots


This Data Function generates Voronoi polygons forming a tessellation that covers study region. Polygons can be used as a feature layer on a map chart.


From input point locations, create Voronoi polygons for Spotfire map visualization. Can produce one Voronoi polygon per input point, or polygons that summarize multiple points. Resulting polygons form a tessellation that covers a study region.

Outline is determined either by convex hull or by optional separate boundary. Coordinates can be specified either as Cartesian (x, y) or Geographic (Longitude, Latitude). Result is an object that can be dragged directly from Spotfire data panel onto a map visualization.

More details about this data function can be found in the community article.
