ParentEdgeStyle

ParentEdgeStyle

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

Details

  • ParentEdgeStyle allows specifying the style of the parent edge 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
    styleuse style for the edge »
    Allstyleuse style for all edges »
    TreeCases[pattern]styleuse style for edges at nodes with data matching pattern »
    "Leaves"styleuse style for edges at leaves »
    "NonLeaves"styleuse style for edges at non-leaves »
    {pos1style1,pos2style2,…}use stylei for the edge at relative position posi »
    {patt1lbl1,patt2lbl2,…}use stylei for edges at positions matching the pattern patti »
  • Subtrees with no explicit edge style posstyle are taken to use the automatic style.
  • ParentEdgeStyle can apply to lines and faces.
  • To specify multiple style directives, use Directive[style1,style2,…].
  • Edge style specifications are effectively applied in the order ParentEdgeStyle, ParentEdgeStyleFunction and ParentEdgeShapeFunction, with later specifications overriding earlier ones.

Style an individual edge:

Specify a list of edge styles:

Use the same style for all edges:

Specify styles for the leaf and non-leaf edges:

Specify positions using data patterns:

Properties & Relations  (4)

Styles for edges 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 position {i,j,…} that match patt:

A list of patterns {patt1,patt2,…} applies to relative positions {i,j,…} that match patti:
