	Back to Chart Types

Voronoi polygons are close relatives of Delaunay triangles, and are used to study the area of influence of each point. Aabel provides the following Voronoi chart types:

Plain Voronoi
Polygons color coded by calculated area
Polygons color coded by values of a third variable
Polygons color coded by area-normalized values of Z
