我正在重新创建工作表以证明我知道各种函数的定义域和范围。我提供的代码给出了图片中显示的一个函数的示例。有人可以向我展示如何在页面上均匀分布 9 个数字，并使用我的代码中的数字作为示例吗？

答案1

我假设您对这九幅图的代码感到满意，因此剩下的任务就是将这九幅图分组到一页上。我建议您创建一个专用环境，例如“smallpic”，来存放每个文件和相关文本。这样，您就可以省去很多重复的输入工作。

在此处输入图片描述

\documentclass[12pt]{article}

\usepackage[demo]{graphicx} % remove 'demo' option in real document
\usepackage{caption}
\newenvironment{smallpic}{\begin{minipage}{0.3\textwidth}\small}
  {\end{minipage}}

\usepackage{pgfplots}

\begin{document}

\begin{figure}
\caption{Nine graphs} \label{fig:ninegraphs}

\begin{smallpic}  % Fig. 1

\begin{tikzpicture}
\begin{axis}[
width = 5.6cm,
height = 5cm,
axis y line = middle, 
axis x line = middle,
grid style = {dashed, gray!50},  
grid = both, % Switch on the grid lines
%ymajorgrids = true,
%xmajorgrids = true,  
minor ytick = {-7,-6,...,3},
minor xtick = {-5,-4,...,5},
xmin = -5,
xmax = 5,
ymin = -7,
ymax = 3,    
%xlabel = $x$,
%ylabel = $y$,
]
\node at (axis cs:-2.45,-5) [blue]{$\bullet$};
\node at (axis cs:2.45,-5) [blue]{$\bullet$};
\addplot[smooth, blue, thick, domain = -2.45:2.45] {-x^2 + 1};
\end{axis}
\end{tikzpicture}

D: $-2.4 \leq x \leq 2.4$

R: $-5 \leq y \leq 1$

This is a parabola.

答案2

您可以使用minipages将文本放置在其中0.3\linewdith，并使用\resizebox{}{}{}缩放图形以适合minipage：

在此处输入图片描述

笔记：

  • 由于您不希望图像浮动，所以不要使用诸如之类的浮动环境figure。
  • 应将标题添加在外面，\resizebox{}{}{}以便文本不被缩放。
  • \vfill用于垂直展开图形。
  • 包裹showframe​ 仅用于显示页边距。实际使用中不需要它。

代码：

如果你要绘制所有内容，那么使用groupplots

 \documentclass[margin=5mm]{standalone}
        \usepackage{pgfplots}
        \usetikzlibrary{positioning}
        \usepgfplotslibrary{groupplots}
        \pgfplotsset{compat=1.11}
        \begin{document}

        \begin{tikzpicture}
                \begin{groupplot}[group style={group name=my plots,group size= 3 by 3,vertical sep=2.5cm },height=5cm,width=6.4cm]
                        \nextgroupplot[title=type1,ylabel={Range1 }]
                                        \addplot[blue] {x};\label{plots:plot1}
                                        \addplot[red] {x²};\label{plots:plot2}
                                        \addplot[green] {2*x};\label{plots:plot3}

                        \nextgroupplot[title=type2]
                                        \addplot[blue]{x};

                        \nextgroupplot[xlabel={x label}]
                                        \addplot[blue]{x};
                        \nextgroupplot[xlabel={x label}]

                \node[below = 0.9cm of my plots c1r3.south] {(g)};
                \node[below = 0.9cm of my plots c2r3.south] {(h)};
