MaxDisplayedChildren

is an option for Tree and related functions that specifies the maximum number of children that should be displayed for each subtree.

Details

  • MaxDisplayedChildren allows the children of the root node of a tree to be elided, as well as those of any subtrees at positions matching a pattern.
  • The following option settings can be used:
  • Automaticdisplay the default number of children
    mdisplay m children for the node »
    Allmdisplay m children for all nodes »
    TreeCases[pattern]mdisplay m children for nodes with data matching pattern »
    {pos1m1,pos2m2,…}display mi children for the node at relative position posi »
    {patt1m1,patt2m2,…}display mi children for nodes at positions matching patti »
  • The global variable $MaxDisplayedChildren gives the default number of children for all nodes.

Examples

open all close all

Basic Examples  (3)

Display all children of the root node:

Display five children:

Display two children for all nodes:

Specify a list of max child numbers:

Scope  (2)

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (6)

Ten children are displayed by default:

Setting $MaxDisplayedChildren=m specifies the default number of children to display for the option setting MaxDisplayedChildrenAutomatic:

Restore $MaxDisplayedChildren to its default:

Maximum children for nodes can be specified by position:

Specify the maximum number of children for a tree:

Maximum children specified by a subtree take precedence over those 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:
