ExpressionTreePlot

As of Version 10, all the functionality of the GraphUtilities package is built into the Wolfram System. »

ExpressionTreePlot[e]

plots the expression tree of e.

ExpressionTreePlot[e,pos]

plots the expression tree of e with its root placed at position pos.

ExpressionTreePlot[e,pos,lev]

plots the expression tree of e up to level lev with its root placed at position pos.

Basic Examples  (2)

Wolfram Language code: Needs["GraphUtilities`"]

An expression tree plot, with tooltips for each vertex giving the subexpression from that vertex down:

Wolfram Language code: ExpressionTreePlot[x ^ 2 + E ^ x + Sin[x]Cos[x]]

ExpressionTreePlot has been superseded by TreeForm:

Wolfram Language code: TreeForm[x ^ 2 + E ^ x + Sin[x]Cos[x]]

Scope  (2)

When Hold, HoldForm, etc. are used, the expressions inside them are not evaluated:

Wolfram Language code: Needs["GraphUtilities`"]
Wolfram Language code: ExpressionTreePlot[Hold[1 + 2 + 3]]

An expression tree up to level 2 with its root at the left:

Wolfram Language code: ExpressionTreePlot[x ^ 2 + E ^ x + Sin[x]Cos[x], Left, 2]

Options  (1)

This gives an expression tree with no vertex labels, except that all subexpressions are shown as tooltips:

Wolfram Language code: Needs["GraphUtilities`"]
Wolfram Language code: ExpressionTreePlot[Integrate[1 + 1 / (x ^ 3 + 1), x], VertexLabeling -> Automatic]

Applications  (1)

This plots a binary tree:

Wolfram Language code: Needs["GraphUtilities`"]
Wolfram Language code: ExpressionTreePlot[Nest[{#, #}&, x, 4], VertexLabeling -> Automatic]

This plots a 5-ary tree:

Wolfram Language code: ExpressionTreePlot[Nest[{#, #, #, #, #}&, x, 3], Center, VertexLabeling -> Automatic, AspectRatio -> 1]

Properties & Relations  (1)

Wolfram Language code: Needs["GraphUtilities`"]

TreeForm also gives the expression tree, although the orientation of the tree cannot be specified:

Wolfram Language code: expr = x ^ 2 + E ^ x + Sin[x]Cos[x];
Wolfram Language code: TreeForm[expr]

ExpressionTreePlot can specify root position:

Wolfram Language code: ExpressionTreePlot[expr, Center]
