MaxDisplayedChildren

[Experimental]

✖

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.
