为何我无法将我的图形放置在我想要的位置？

Question

我有一些文本，之后我想插入一个图形。文本几乎在第二页上结束，所以我想将图形放在第三页的顶部（紧接着文本），但我不能。我已从这里阅读了放置命令：http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions我尝试了所有不同的选项（即 \begin{figure}[t!]、\begin{figure}[t]、\begin{figure}[b]、\begin{figure}[h] 等），但图形仍然停留在第三页中间的同一位置。我想让它位于顶部。我遗漏了什么？以下是代码：

Answer 1

目前，您的文档中没有足够的文本供 LaTeX 将图形放在页面顶部。在第一页上，顶部的浮动是被禁止的。没有第二页（文本）。因此，如果将图形留在文档末尾，LaTeX 会尽一切可能将其放置：它会将其放在浮动页面上，默认情况下，这意味着浮动在页面上垂直居中。

如果图后有更多文字，则不会发生这种情况：

\documentclass[11pt]{article}
\usepackage{kantlipsum}% for the demo
\usepackage{amssymb,mathtools}% fixes/enhancements for amsmath (loads amsmath)
\usepackage[demo]{graphicx}
\usepackage{tikz}

\usepackage{fullpage}
\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage{algpseudocode}
\newtheorem{thm}{Theorem}
\newtheorem{thm1}{Theorem}
\theoremstyle{definition}
\usepackage{float}
\newtheorem{defn}{Definition}[section]
\floatname{algorithm}{Algorithm}
\newcommand{\euler}{e}
\newenvironment{claim}[1]{\par\noindent\underline{Claim:}\space#1}{}

如果您希望图形位于中心，请\centering在环境的开始处添加figure`。

如果这是文档的末尾，您可以\newpage\vfill\mbox{ }在末尾添加一个新页面，否则将空白页，以便图形浮动到顶部。

Answer 2

\usepackage{float}

\begin{figure}[H]

这将强制 LaTex 将图形放在您想要的位置。
