TreeElementSizeFunction

TreeElementSizeFunction

is an option for Tree and related functions that specifies a function to use to generate sizes for subtree elements.

Details

  • TreeElementSizeFunction allows specifying the function to generate the size of the root node of a tree, as well as that of any subtree at positions matching a pattern.
  • The following option settings can be used:
  • Automaticautomatically compute node size
    funca general node size function »
    Allfuncuse size function func for all nodes »
    TreeCases[pattern]funcuse func for nodes with data matching pattern »
    "Leaves"funcuse func for leaves »
    "NonLeaves"funcuse func for non-leaves »
    {pos1func1,pos2func2,…}use funci at relative position posi »
    {patt1func1,patt2func2,…}use funci at positions matching the pattern patti »
  • TreeElementSizeFunction specifications override TreeElementSize specifications.
  • TreeElementSizeFunctionfunc specifies that the size of the root node should be provided by func[data], where data is the data in the root.

Basic Examples  (4)

Generate an individual node size:

Specify a list of node size functions:

Use the same size function for all nodes:

Specify size functions for the leaves and for the non-leaves:

Scope  (2)

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (4)

Sizes for nodes can be specified by position:

Sizes specified by a subtree take precedence over sizes 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 patti:
