UnlabeledTree

UnlabeledTree[tree]

returns a tree of the same shape as tree in which the nodes and edges are displayed without labels.

Details and Options

Examples

open all close all

Basic Examples  (2)

Remove all labels from a tree:

Wolfram Language code: UnlabeledTree[[image]]

Remove edge labels:

Wolfram Language code: UnlabeledTree[[image]]

Options  (4)

Styling Individual Tree Elements  (1)

Specify the label for the generated tree element:

Wolfram Language code: UnlabeledTree[[image], TreeElementLabel -> "?"]

Tree Layout and Graphics Options  (3)

Specify the orientation for the root:

Wolfram Language code: UnlabeledTree[[image], TreeLayout -> Bottom]

Specify a named embedding:

Wolfram Language code: UnlabeledTree[[image], TreeLayout -> "BalloonEmbedding"]

Specify Graphics options:

Wolfram Language code: UnlabeledTree[[image], Background -> LightBlue, ImageSize -> 50]

Properties & Relations  (2)

UnlabeledTree overrides TreeElementLabel and ParentEdgeLabel specifications given by subtrees:

Wolfram Language code: Tree[{Tree[None, ParentEdgeLabel -> "edge"]}, TreeElementLabel -> "node"]
Wolfram Language code: UnlabeledTree[%]

UnlabeledTree[ExpressionTree[expr]] removes all data and labels from an expression tree:

Wolfram Language code: UnlabeledTree[ExpressionTree[f[g[1, 2], x]]]

ExpressionTree[expr,Null] gives an expression tree with no data directly:

Wolfram Language code: ExpressionTree[f[g[1, 2], x], Null]
