Here, several lines per node is allowed by
\tikzset{style={align=center,anchor=north}}
but this messes up the tree (the length of the branches).
Can this be remedied?

[Stefan Kottwitz]

You could apply the style locally, where needed.

I would define a multi-line style, so it's easier to adjust and better readable in the tree code:

Code: Select all

1
\tikzset{multiline/.style={align=center,anchor=north}}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

In the tree, you can write the node with this style, where needed, such as

Code: Select all

1
... [ .\node [multiline] {d\\f\\g\\h}; [ ...
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה

Furthermore, you probably need to adjust the level distance, because multi-line nodes are higher.

It seems impossible to change the level distance for individual nodes inside the tree.

Perhaps the problem could be solved if the new lines could be added below the first instead of above it, but I don't know if this is possible -- ?

[Stefan Kottwitz]

David Chiang and Andrew Stacey have improved the tikz-qtree package. Now it's possible to define level based styles, such as level distance and sibling distance. You can try if you add to your code:

Code: Select all

Code, edit and compile here:

1
2
3
\tikzset{level 1/.style={level distance=30pt}}
\tikzset{level 2/.style={level distance=40pt, sibling distance=20pt}}
\tikzset{level 3+/.style={level distance=40pt, sibling distance=10pt}}

You just need to update your package. The new features are documented in the up-to-date tikz-qtree manual, in 3.3 Node placement styles.

Wunderbar! Besten Dank!
