我怎样才能使这棵树缩小到适合标准页面？

Question

 \documentclass{article}     

 \usepackage{tikz}
 \usetikzlibrary{trees}
 \begin{document}     

 % Set the overall layout of the tree
 \tikzstyle{level 1}=[level distance=3.5cm, sibling distance=3.5cm]
 \tikzstyle{level 2}=[level distance=3.5cm, sibling distance=2cm]     

 % Define styles for bags and leafs
 \tikzstyle{bag} = [text width=4em, text centered]
 \tikzstyle{end} = [circle, minimum width=3pt,fill, inner sep=0pt]     

 \begin{tikzpicture}[grow=right, sloped]
 \node[bag] {A-B-B}
     child {
         node[bag] {B}
         child {
                 node[end] {}
             }
             child {
                 node[end] {}
             }
     }
     child {
         node[bag] {A}
             child {
                 node[bag] {B}
             child {
                 node[bag] {B}
             child {
                 node[bag] {B}            
             child {
                 node[bag] {B}
             } 
             } 
             } 
             }            
             child {
                 node[end] {}
             }
     };
 \end{tikzpicture}     

 \end{document}

Answer 1

您的图表太宽，无法适应文本宽度。要解决此问题，您有三种方法：

• 包含横向页面方向的图表

• 重新绘制图形，使其向下（下方）增长，而不是向右

• 使水平距离更小。

最后一种可能性的代码如下。在其中，我还稍微更改了节点选项并添加了选项（作为查看其边框的临时解决方案）draw。在序言中还添加了showframe显示页面布局的包。

\documentclass{article}
 \usepackage{tikz}
 \usetikzlibrary{trees}

 \usepackage{showframe}

 \begin{document}
 % Set the overall layout of the tree
 \tikzstyle{level 1}=[level distance=2cm, sibling distance=3cm]
 \tikzstyle{level 2}=[sibling distance=2cm]

 % Define styles for bags and leafs
 \tikzstyle{bag} = [draw, minimum width=2em, text centered]
 \tikzstyle{end} = [circle, minimum width=3pt,fill, inner sep=0pt]

 \begin{tikzpicture}[grow=right, sloped]
 \node[bag] {A-B-B}
     child {
         node[bag] {B}
         child {
                 node[end] {}
             }
             child {
                 node[end] {}
             }
     }
     child {
         node[bag] {A}
             child {
                 node[bag] {B}
             child {
                 node[bag] {B}
             child {
                 node[bag] {B}
             child {
                 node[bag] {B}
             }
             }
             }
             }
             child {
                 node[end] {}
             }
     };
 \end{tikzpicture}

 \end{document}

当然，在实际使用中您只需省略所有演示边框。
