How can I correctly display my AVL Tree in LaTex? A solo left-child hangs straight down
The below code almost works perfectly, however the child of 9, 7, hangs straight down instead of as a left-child. How can I correct this?
\usepackage{tikz}
\usepackage{xytree}
\begin{tikzpicture}[level/.style={sibling distance=60mm/#1}]
\node [circle,draw] {4}
child {
node [circle,draw] {2}
child {node [circle,draw] {开发者_运维技巧1}
}
child {
node [circle,draw]{3}
}
}
child {node [circle,draw] {6}
child {node [circle,draw] {5}
}
child {node [circle,draw] {9}
child {node [circle, draw] {7}}
}
};
\end{tikzpicture}}
Thanks, CB
The code below works for me. It is based on your code, with the changes
1) use the tikz library trees and 2) change of the formatting of a single node (node 7)
For more information see the tikz manual
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}[level/.style={sibling distance=60mm/#1}]
\node [circle,draw] {4}
child {
node [circle,draw] {2}
child {node [circle,draw] {1}
}
child {
node [circle,draw]{3}
}
}
child {node [circle,draw] {6}
child {node [circle,draw] {5}
}
child {node [circle,draw] {9}
child[grow via three points={one child at (-1,-1) and two children at (-.5,1) and (.5,1)}] {node [circle, draw] {7}}
}
};
\end{tikzpicture}
\end{document}
After consulting with the tikz manual as suggested, I was able to correct this as follows.
\begin{tikzpicture}[level/.style={sibling distance=60mm/#1}]
\node [circle,draw] {4}
child {
node [circle,draw] {2}
child {node [circle,draw] {1}
}
child {
node [circle,draw]{3}
}
}
child {node [circle,draw] {6}
child {node [circle,draw] {5}
}
child {node [circle,draw] {9}
child {node [circle, draw] {7}}
child [missing]
}
};
\end{tikzpicture}
