TreeElementLabelStyle

TreeElementLabelStyle

is an option for Tree and related functions that specifies what styles should be used for subtree element labels.

Details

  • TreeElementLabelStyle allows specifying the label style of the root node of a tree, as well as that of any subtrees at positions matching a pattern.
  • Any style specification as used in Style can be used as a setting for TreeElementLabelStyle.
  • The following option settings can be used:
  • Automaticuse the automatic style
    styleuse style for the node label »
    Allstyleuse style for all node labels »
    TreeCases[pattern]styleuse style for labels of nodes with data matching pattern »
    "Leaves"styleuse style for leaf labels »
    "NonLeaves"styleuse style for non-leaf labels »
    {pos1style1,pos2style2,…}use stylei for the node label at relative position posi »
    {patt1style1,patt2style2,…}use stylei for node labels at positions matching patti »
  • Subtrees with no explicit label style are taken to use the automatic style.
  • Color directives such as Red, as well as text specifications such as Bold or Small, can be given.
  • To specify multiple style directives, use Directive[style1,style2,…].
  • Giving the option setting TreeElementLabelStylestyle is effectively equivalent to replacing the label-like elements of a formatting or related construct by Style[label,style].
  • Subtree element label specifications are effectively applied in the order TreeElementLabel, TreeElementLabelFunction and TreeElementLabelStyle, with later specifications overriding earlier ones.

Basic Examples  (4)

Style an individual node label:

Specify a list of node label styles:

Use the same style for all node labels:

Specify styles for the leaf and non-leaf labels:

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (4)

Styles for node labels 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:
