我有这些代码来绘制图形。但我没有找到另外添加文本的方法。当我写一些东西时，编译器总是给我图形。我想要一个解释性的文字，在这些文字下我想包含以下图画：
\documentclass[11pt]{article}
\usepackage[pdftex,active,tightpage]{preview}
\setlength\PreviewBorder{2mm}
\usepackage{tikz}
\usetikzlibrary{arrows,positioning, calc,lindenmayersystems,decorations.pathmorphing,intersections}
\tikzstyle{resource}= [draw,minimum size=16pt,inner sep=0pt]
\tikzstyle{process} = [draw,minimum size=16pt,inner sep=0pt,circle]
\tikzstyle{allocated} = [->,thick,arrows={-latex}]
\tikzstyle{requested} = [<-,thick,arrows={latex-}, dashed]
\begin{document}
\begin{preview}
\begin{tikzpicture}[scale=2,auto,swap]
\node (p1)[resource] at (1,0) {$P_1$};
\node (p2)[resource] at (1,1) {$P_2$};
\node (p3)[resource] at (1,2) {$P_3$};
\node (a)[process] at (0,2) {$A$};
\node (b)[process] at (2,2) {$B$};
\node (c)[process] at (2,0) {$C$};
\node (d)[process] at (2,1) {$D$};
\draw[allocated] (c) -- (p1);
\draw[allocated] (a) -- (p3);
\draw[allocated] (p1) -- (a);
\draw[allocated] (p2) -- (c);
\draw[allocated] (p3) -- (b);
\draw[allocated] (d) -- (p2);
\end{tikzpicture}
\end{preview}
\end{document}
编辑： 我只想要这样的东西。使用简单的图像不会有问题，但我不知道如何包含 tikz 图形：
答案1
你的问题一点都不清楚。我怀疑你问的是，如何在文本中包含图片。除了提供的解决方案比基·特隆答案有一些好处：图像位于文本中插入的位置，但是，如果页面上插入的位置不够，就会出现漏洞。然后它会移到下一页，并在前一页上留下空白。为了解决这个问题，(La)TeX 有浮动功能，它试图通过图像浮动将图像放置在文本中的最佳位置。
例如，就你的情况而言：
\documentclass[11pt]{article}
\usepackage{tikz}
\usetikzlibrary{arrows}
\tikzset{
base/.style = {draw, minimum size=16pt, inner sep=0pt},
resource/.style = {rectangle, base},
process/.style = {circle, base},
allocated/.style = {-latex, thick},
%requested/.style = {latex-, thick, dashed}
}% end of tikzset
\setlength\parindent{0pt}
\usepackage{lipsum}% for dummy text filler
\begin{document}
\lipsum[11]
\begin{figure}[htb]
\centering
\begin{tikzpicture}[scale=2]
\node (p1) [resource] at (1,0) {$P_1$};
\node (p2) [resource] at (1,1) {$P_2$};
\node (p3) [resource] at (1,2) {$P_3$};
%
\node (a) [process] at (0,2) {$A$};
\node (b) [process] at (2,2) {$B$};
\node (c) [process] at (2,0) {$C$};
\node (d) [process] at (2,1) {$D$};
%
\draw[allocated]
(d) edge (p2)
(p2) edge (c)
(c) edge (p1)
(p1) edge (a)
(a) edge (p3)
(p3) edge (b);
\end{tikzpicture}
\caption{my graph}
\label{fig:my graph}
\end{figure}
\lipsum[2]
\end{document}
生成：
使用上述任何一种解决方案都与包含图的复杂性无关。Tikz 代码可以直接在figure浮点环境中，也可以包含在内，例如
\input{path/<code-file-name>}
图表的唯一限制是其大小。生成的图像应小于一页的文本区域。
如果您想在图像中添加一些文字作为图例，您也可以通过以下方式进行：
...
\begin{document}
\lipsum[1]
\begin{figure}[htb]
\centering
\begin{tikzpicture}[scale=2]
\node (p1) [resource] at (1,0) {$P_1$};
\node (p2) [resource] at (1,1) {$P_2$};
\node (p3) [resource] at (1,2) {$P_3$};
%
\node (a) [process] at (0,2) {$A$};
\node (b) [process] at (2,2) {$B$};
\node (c) [process] at (2,0) {$C$};
\node (d) [process] at (2,1) {$D$};
%
\draw[allocated]
(d) edge (p2)
(p2) edge (c)
(c) edge (p1)
(p1) edge (a)
(a) edge (p3)
(p3) edge (b);
\end{tikzpicture}
\medskip
\begin{minipage}{\linewidth}% text in figure environment
\textbf{Legend:} \lipsum*[11]
\end{minipage}
\caption{my graph}
\label{fig:my graph}
\end{figure}
\lipsum[2]
\end{document}
这使：
一些文档类为这种情况提供了特殊环境，例如legend在包中memoir。
笔记：
我以更简洁的形式重写了给定的图表示例。在这里，我用 替换了过时的
\tikzstyle符号tikzset。我强烈建议你作为 LaTeX 新手阅读一些 LaTeX 介绍文本。例如LATEX 2ε 的简短介绍，或者其他一些。
