link.delaunay Function (GPL)

Syntax

link.delaunay(<algebra>)

or 

link.delaunay(<binning function>)

or 

link.delaunay(<statistic function>)

<algebra>. Graph algebra, such as x*y. Refer to Brief Overview of GPL Algebra for an introduction to graph algebra.

<binning function>. A binning function.

<statistic function>. Another statistic function. The result of the embedded statistic is used to calculate link.delaunay.

Description

Calculates the Delaunay triangulation for the values. This function is typically used with the edge graphic element. The triangulation connects all values so that the connecting segments form triangles.

Examples

ELEMENT: edge(position(link.delaunay(x*y)))
