把所有东西都放在同一条线上

所以我想把下面的图放在同一行。我的工作代码是这样的：

\documentclass{article} % say
\usepackage{tikz}

    };

    \end{tikzpicture}
    \caption{0$<$k$<$1} 
\end{figure}

        \filldraw [colorforline] (3,0) circle [radius=2pt] node[below] {

        };

        \end{tikzpicture}
        \caption{k$>$1} 
    \end{figure}
\end{document}

这给了我这个结果：

在此处输入图片描述

但我希望它是这样的：

在此处输入图片描述

现在我注意到图片的尺寸可能很大，无法将它们放在同一行，但还有其他方法吗？比如缩小一点或动态设置大小而不改变坐标，这对我来说会很麻烦，因为我已经做了很多这样的工作

使用以下解决方案minipage：

您不能使用figure。minipage您可以改用\usepackage{caption}我还使用adjustbox来调整图像：

答案2

如果你确实想要在同一行上显示三个单独的图形，flav 的答案非常好。如果你真的想将三幅图像合并为一个带有一个数字和标题的图形，请尝试subcaption包。如果您根本不想要单独的标题，您也可以将所有三张图片放在同一张图中。

我在上面的评论中也提到过，有几种方法可以缩放图片，具体取决于您的意图。您可以 a) 向环境tikzpicture本身添加缩放因子，或者 b) 在渲染图片后缩放图片。第一种方法将使某些元素不缩放，例如文本和线宽，而第二种方法会缩放所有内容。

我在下面说明了这些不同的方法（为了简洁起见，使用了更简单的虚拟图片）。

\documentclass{article} % say
\usepackage{tikz,changes,amsmath,subcaption}
\begin{document}
\begin{figure}
  \begin{subfigure}[b]{.3\linewidth}
    \centering
    \[
    \begin{bmatrix}
    k & 0 \\
    0 & 1
    \end{bmatrix}
    \]
    \caption{Standard Matrix}
    \label{subfig:matrix}
  \end{subfigure}
  \hfill
  \begin{subfigure}[b]{.3\linewidth}
    \centering
    \begin{tikzpicture}[scale=.5]
      \draw[very thick] (0,0) rectangle node {$0<k<1$} (5,3);
    \end{tikzpicture}
    \caption{$0<k<1$}
    \label{subfig:smallk}
  \end{subfigure}
  \hfill
  \begin{subfigure}[b]{.3\linewidth}
    \centering
    \begin{tikzpicture}[scale=.5]
      \draw (0,0) node[above right] {Text} rectangle (5,5) node[below left] {$x\geq 3$};
    \end{tikzpicture}
    \caption{$k>1$}
    \label{subfig:largek}
  \end{subfigure}
  \caption{Three figures arranged using \texttt{subcaption} with scaling directly on the \texttt{tikzpicture} environments.}
  \label{fig:first}
\end{figure}
Using \texttt{subcaption}, you can refer to subfigures \ref{subfig:matrix}, \ref{subfig:smallk}, \ref{subfig:largek}, or figure \ref{fig:first}. You can even refer to subfigure \subref{subfig:matrix} of figure \ref{fig:first}.

\begin{figure}
  \centering
  $\displaystyle % This gets the styling of math display mode without the line breaks.
  \begin{bmatrix}
  k & 0 \\
  0 & 1
  \end{bmatrix}
  $
  \hfill
  \scalebox{.5}{
  \begin{tikzpicture}
    \draw[very thick] (0,0) rectangle node {$0<k<1$} (5,3);
  \end{tikzpicture}
  }
  \hfill
  \scalebox{.5}{
  \begin{tikzpicture}
    \draw (0,0) node[above right] {Text} rectangle (5,5) node[below left] {$x\geq 3$};
  \end{tikzpicture}
  }
  \caption{The same three figures with no subcaption, scaled using \texttt{scalebox}.}
  \label{fig:second}
\end{figure}

Without \texttt{subcaption}, you can only refer to figure \ref{fig:second}.

\end{document}

（请注意，参数[b]表示subfigure图形应该底部对齐。）
