TreeElementCoordinates

TreeElementCoordinates

is an option for Tree and related functions that specifies the coordinates to use to place the center of subtree elements.

Details

  • TreeElementCoordinates allows specifying the coordinates of the root node of a tree, as well as that of any subtrees at positions matching a pattern.
  • The following settings for TreeElementCoordinates can be used:
  • Automaticautomatically compute node coordinates
    ptplace the root node at center coordinate pt
    Allptplace all nodes at center coordinate pt
    TreeCases[pattern]ptplace nodes with data matching pattern at center coordinate pt
    {pos1pt1,pos2,…}place the node at relative position posi at center coordinate pti
    {patt1pt1,patt2pt2,…}place the nodes at positions matching patti at center coordinate pti
  • With the setting TreeElementCoordinatesAutomatic, the center coordinates for subtree elements are computed according to the setting for TreeLayout.

Specify coordinates for an individual node:

Specify a list of node coordinates:

Use the same coordinates for all nodes:

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (4)

Coordinates for subtree elements can be specified by position:

Sizes specified by a subtree take precedence over sizes specified by its ancestors:

A position {i,j,…} in a subtree refers to its subtree at relative position {i,j,…}:

A relative position {2} at position {1} refers to the global position {1,2}:

In general, a pattern patt applies to subtrees at global positions {i,j,…} that match patt:

A list of patterns {patt1,patt2,…} applies to relative positions {i,j,…} that match patti:
