TreeElementCoordinates

[Experimental]

✖

is an option for Tree and related functions that specifies the coordinates to use to place the center of subtree elements.

Details

  • TreeElementCoordinates allows specifying the coordinates 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:
  • Automaticautomatically compute node coordinates
    ptplace the node at center coordinate pt »
    Allptplace all nodes at center coordinate pt »
    TreeCases[pattern]ptplace nodes with data matching pattern at center coordinate pt »
    "Leaves"ptplace leaves at center coordinate pt »
    "NonLeaves"ptplace non-leaves at center coordinate pt »
    {pos1pt1,pos2pt2,…}place the node at relative position posi at center coordinate pti »
    {patt1pt1,patt2pt2,…}place nodes at positions matching patti at center coordinate pti »
  • With the setting TreeElementCoordinatesAutomatic, the center coordinates for subtree elements are computed according to the setting for TreeLayout.
