forest tree nodes












3















I'd like to clean up my tree by drawing an edge between parent nodes. In the following, I'd like to have the 0 nodes (which are children now) adjacent to the numbered nodes (ie on the "parent" level). How might I do this? Am I missing something simple? Thanks!



documentclass{article}
usepackage{forest}
begin{document}

begin{forest}
for tree={circle, draw, l sep=20pt, s sep=5 mm}
[0, green
[0, green]
[1, red
[0, green]

[1, red
[0, green]
[2, red]
]
[2, red
[0, green]
[1, red]
]
]
]
end{forest}
end{document}


by letting each 0 node be on the same level as the parents and connecting the parent.



That is, I'd like it to look something like

  • Normally you can achieve this by adding appropriate tiers but in your tree the 0 nodes occur at all levels.

  • @marmot: would it be possible to do that just with the first 0 node, for example? As in adding two 0 nodes at the top level, one with the remaining full tree, and one which is the final node?

  • You could try documentclass{article} usepackage{forest} begin{document} begin{forest} for tree={circle, draw, l sep=20pt, s sep=5 mm} [0, green [0, green,tier=murmel] [1, red [0, green,tier=murmel] [2, red [0, green] [3, red] ] [3, red [0, green] [2, red] ] ] (rest of your tree start with [2, red) end{forest}end{document} but this doesn't look convincing to me. This is not because forest cannot do it, but because I do not understand your request.

    @rrrrr What do you mean by "annotate"? Like putting labels on the edges? If so, always the same? (One can put labels on the path with draw (LX) -- ++ (-1.5cm,0) node[circle,left,draw,green]{0} node[midway,above]{text};.)

Not a tikz-tree solution: I just try to replicate your graph using normal TikZ



documentclass[tikz,margin=3mm]{standalone}
usetikzlibrary{calc}
begin{document}
begin{tikzpicture}
node [circle,draw] (0c) at (0,0) {0};
node [circle,draw] (1) at ($(0c)+(-120:1.5)$) {1};
node [circle,draw] (2r) at ($(0c)+(-60:1.5)$) {2};
node [circle,draw] (2l) at ($(1)+(-120:1.5)$) {2};
node [circle,draw] (3) at ($(1)+(-60:1.5)$) {3};
node [circle,draw] (0al) at ($(0c)+(-1.5,0)$) {0};
node [circle,draw] (0bl) at ($(1)+(-1.5,0)$) {0};
node [circle,draw] (0r) at ($(2r)+(1.5,0)$) {0};
draw (0c)--(1)
(0c)--(2r)

    • As a follow-on, how might I annotate the aliased edges to from nonzero to 0 nodes?

      @rrrrr What do you mean by "annotate"? Like putting labels on the edges? If so, always the same? (One can put labels on the path with draw (LX) -- ++ (-1.5cm,0) node[circle,left,draw,green]{0} node[midway,above]{text};.)
