TreeLayout

TreeLayout

is an option to Tree and related functions that specifies what layout to use.

Details

  • TreeLayout allows the same tree to be graphically displayed in different orientations and two-dimensional embeddings.
  • Possible layouts include:
  • Automaticautomatically select a layout
    posorientation with the root at position pos
    "emb"named embedding
  • Possible orientation positions pos include:
  • Toproot at the top
    Bottomroot at the bottom
    Leftroot on the left
    Rightroot on the right
  • Possible named embeddings "emb" include:
  • "BalloonEmbedding"subtrees on a circle with the center at the parent
    "RadialEmbedding"subtrees on a circular segment
    "LayeredEmbedding"subtrees on parallel lines
    "LayeredDigraphEmbedding"subtrees on parallel lines, with alternative suboptions

Basic Examples  (2)

Orient the tree with the root to the left:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> Left]

Specify a named embedding:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> "BalloonEmbedding"]

Scope  (5)

Orientations  (1)

Specify the orientation of the root:

Wolfram Language code: Table[Tree[[image], TreeLayout -> orientation, PlotLabel -> orientation], {orientation, {Top, Bottom, Left, Right}}]

"BalloonEmbedding"  (1)

Specify a balloon embedding:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> "BalloonEmbedding"]
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"BalloonEmbedding", "EvenAngle" -> #}]& /@ {True, False}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"BalloonEmbedding", "OptimalOrder" -> #}]& /@ {True, False}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"BalloonEmbedding", "RootVertex" -> #}]& /@ {{}, {2}, {2, 2}}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"BalloonEmbedding", "Rotation" -> #}]& /@ {45Degree, 30Degree}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"BalloonEmbedding", "SectorAngles" -> {1 -> Pi / 2}}]

"RadialEmbedding"  (1)

Specify a radial embedding:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> "RadialEmbedding"]
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"RadialEmbedding", "RootVertex" -> #}]& /@ {{}, {2}, {2, 2}}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"RadialEmbedding", "Rotation" -> #}]& /@ {0, 30, 60, 90}

"LayeredEmbedding"  (1)

Specify a layered embedding:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> "LayeredEmbedding"]
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredEmbedding", LayerSizeFunction -> #}]& /@ {5&, 10&}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredEmbedding", "RootVertex" -> #}]& /@ {{}, {2}, {2, 2}}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredEmbedding", "LeafDistance" -> #}]& /@ {1, 2, 3}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredEmbedding", "Orientation" -> #}]& /@ {Top, Bottom, Left, Right}

"LayeredDigraphEmbedding"  (1)

Layered digraph embedding:

Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> "LayeredDigraphEmbedding"]
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredDigraphEmbedding", "RootVertex" -> #}]& /@ {{}, {2}, {2, 2}}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredDigraphEmbedding", "Rotation" -> # * Degree}]& /@ {30, 60, 90, 120}
Wolfram Language code: Tree[1, {[image], [image], [image]}, TreeLayout -> {"LayeredDigraphEmbedding", "Orientation" -> #}]& /@ {Top, Bottom, Left, Right}
