TreeElementShape

TreeElementShape

is an option for Tree and related functions that specifies what graphics should be used for subtree elements.

Details

  • TreeElementShape allows specifying the shape of the root node of a tree, as well as that of any subtree at positions matching a pattern.
  • TreeElementShape can be any Graphics, Graphics3D or Image object.
  • The center of the object lies at the position in the graphic specified by TreeElementCoordinates. »
  • The rendered form of each subtree element is obtained by rescaling the given object as specified by TreeElementSize. »
  • The following option settings can be used:
  • Automaticuse the automatic shape
    guse the graphic g for the node »
    Allguse g for all nodes »
    TreeCases[pattern]guse g for nodes with data matching pattern »
    "Leaves"guse g for leaves »
    "NonLeaves"guse g for non-leaves »
    {pos1g1,pos2g2,…}use gi for the node at relative position posi »
    {patt1g1,patt2g2,…}use gi for nodes at positions matching patti »
  • TreeElementShapeFunction specifications override TreeElementShape specifications. »

Basic Examples  (4)

Specify an individual node shape:

Specify a list of node shapes:

Use the same shape for all nodes:

Specify shapes for the leaves and for the non-leaves:

Scope  (2)

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (7)

The center of the object lies at the position in the graphic specified by TreeElementCoordinates:

TreeElementShape can be combined with TreeElementSize:

TreeElementShapeFunction specifications override TreeElementShape specifications:

Shapes for nodes can be specified by position:

Styles specified by a subtree take precedence over styles 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 the patti:

Possible Issues  (1)

TreeElementShape takes graphics or images used for nodes:

TreeElementShapeFunction requires Inset to render graphics or an image:
