TreeElementStyleFunction

TreeElementStyleFunction

is an option for Tree and related functions that specifies functions to use to generate subtree element styles.

Details

  • TreeElementStyleFunction allows specifying the function to generate the style of the root node of a tree, as well as that of any subtrees at positions matching a pattern.
  • The following option settings can be used:
  • Automaticuse the automatic style
    funca general node style function »
    Allfuncuse node style 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 for the node at relative position posi »
    {patt1func1,patt2func2,…}use funci for nodes at positions matching patti »
  • Subtree element style specifications are effectively applied in the order TreeElementStyle, TreeElementStyleFunction and TreeElementShapeFunction, with later specifications overriding earlier ones.
  • TreeElementStyleFunctionfunc specifies that the style of the root node should be provided by func[data], where data is the data in the root.

Basic Examples  (4)

Generate a style for an individual node:

Specify a list of node style functions:

Use the same style function for all nodes:

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

Scope  (2)

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (4)

Styles for nodes can be specified by position:

Styles specified by a subtree take precedence over styles 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:
