所以我在绘制我创建的自动机时遇到了一些麻烦。我找了好一阵子，但一无所获，所以我决定自己问这个问题：当我制作一个自动机（我会发布我的自动机）时，整个图表都太靠右了。考虑到我的默认间距是 3.5 厘米，整个图表都清晰可见，没有任何东西被切断，但是当我希望将节点间距再拉大一点，比如说 5.5 厘米时，我的自动机的一半就会从屏幕右侧掉下来（即它似乎永远不会被绘制出来）。
我曾尝试改变第一个节点的起始位置，假设“其他每个节点都是围绕第一个节点构建的”，但那没有用。我试过使用at (x, y)，我试过使用\centering，我试过很多东西（其中一半来自这个网站），但遗憾的是，我无法弄清楚。以下是代码：
\documentclass[a4paper,10pt]{article}
%as of the 20th f August, 2013, all of the self-loops
%for all of the nodes are incomplete (ie if any
%nodes have self loops, the labels are not quite finished)

答案1
您有以下几种选择：
增加纸张尺寸：
可能不是一个可行的选择，但是为了完成：请参阅LaTeX 维基百科以获取详尽列表。
降低边距：
\usepackage[margin=1pt]{geometry}
在这种情况下，根本就没有足够的空间。
使用standalone类：
将图像外部化到不同的文件中。
\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,automata, positioning}
\usepackage[latin1]{inputenc}
\begin{document}
\begin{tikzpicture}[...]
...
这样可以将所有内容放在一页上，并可轻松将其包含在主文档中，\includegraphics[width=\textwidth]{mytikzautomaton}
这也可以加快主文档的编译速度相当。
缩放整个绘图：
这需要相当多的调整才能看起来不错，并且不是一个非常强大的解决方案，但需要最少的努力。
\begin{tikzpicture}[..., scale=0.9,
every node/.style={scale=0.9}]
...
完整示例使用standalone：
\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,automata, positioning}
\usepackage[latin1]{inputenc}
\begin{document}
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=5.5cm,
semithick,
scale=0.9, every node/.style={scale=0.9}]
\tikzstyle{every state}=[fill=red,draw=none,text=white]

\node[state] (2) [below of=1] {$s_2$};
\node[state] (3) [above left of=1] {$s_3$};
\node[state] (4) [above right of=1] {$s_4$};
\node[state] (5) [below left of=3] {$s_5$};
\node[state] (6) [below right of=4] {$s_6$};
\node[state] (7) [below of=2] {$s_7$};
\node[state] (8) [below of=5] {$s_8$};
\node[state] (9) [below of=6] {$s_9$};
