创建 tikz 图片 | 箭头和标签的问题

我对 Ti 还很陌生钾Z 和我想要为我的测量类创建一个图表。我创建了以下图片：

\documentclass{standalone}
\usepackage{float}
\usepackage{amsfonts}
\usepackage{mathrsfs}
\usepackage{tikz}
\begin{document}
   \begin{tikzpicture}[scale=1.5]
        %Mis espacios
        \node (A) at (0,3) {$(\Omega, \mathscr{F},\mu)$};
        \node (B) at (3,3) {$(\Omega',\mathscr{F}')$};
        \node (C) at (3,0) {$(\mathbb{R}^1,\mathscr{R}^{1})$};
        %Los mapas
        \draw [thick,->] (A) to  node[midway,above] {$T$} (B);
        \draw [thick,->] (B) to node[midway,right] {$f$} (C);
        \draw [dashed,thick,->] (A) to node[midway,above left, yshift=-13 pt] {$T \circ f$} (C);
    \end{tikzpicture}
\end{document}

问题说明

但是，我在执行代码时遇到了问题，因为组合标签出现在箭头上方，而箭头提示却没有出现。

下面的代码包含了我原来拥有的所有包，以防某些包与我的图片不兼容。

另外，我想包含出现在我的原始文档中的错误：

Runaway argument?
Missing \endcsname inserted.

答案1

附件中列出了您拥有的几个选项。您可能希望在 pgfmanual 中查找它们，例如通过索引、查找等。我指出了代码中的更改，包括\section和一些视觉更改comment。选项transform shape和scale可能是您遗漏的选项。

结果

答案2

我发现语言包会影响>箭头中字符的使用，因此您可以尝试使用普通 tikz 提供的其他类型的定义，或者您可以使用示例中的元箭头。我建议您查看tikz 视觉手册第 21 和 56 页。

\usepackage{amsthm}
\usepackage{mathtools}
\usepackage[spanish]{babel} %<---Here this throws an error using the ">" symbol for arrows, try using arrows.meta
\usepackage{mathrsfs}
\usepackage{float}
\usepackage{amsfonts}
\usepackage{mathrsfs}
\usetikzlibrary{arrows.meta} %<--- 
\begin{document}

   \begin{tikzpicture}[]
        %Mis espacios
        \node (A) at (0,3) {$(\Omega, \mathscr{F},\mu)$};
        \node (B) at (3,3) {$(\Omega',\mathscr{F}')$};
        \node (C) at (3,0) {$(\mathbb{R}^1,\mathscr{R}^{1})$};
        %Los mapas
         \draw [thick,-Classical TikZ Rightarrow] (A) to  node[midway,above] {$T$} (B);
        \draw [thick,-To] (B) to node[midway,right] {$f$} (C);
        \draw [dashed,thick,-Triangle] (A) to node[midway,sloped,above] {$T \circ f$} (C);
    \end{tikzpicture}
\end{document}

顺便说一句，我没有发现您列出的其他软件包存在任何其他不兼容性，这些软件包当然是您的主文档所必需的，在独立的 tikz 环境中，它可以在开始时声明，而 tikz 本身会调用其他软件包，如 xcolor，当然如果它是最终图像应该在您的主文档中管理，就像它是一张普通图像一样，只是您必须以 pdf 格式导入它，这样您就可以缩放、旋转它，甚至嵌套它，您可以在很久以前的以下帖子中看到这一点：将 tikzpicture 的不同组件缩放在一起

答案3

使用tikz-cd包。

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{tikz-cd}
\usepackage{mathrsfs}

\begin{document}
\begin{tikzcd}[row sep =1.5cm]
{(\Omega, \mathscr{F},\mu)} \arrow[rd, "T\circ f"{sloped}, dashed] \arrow[r, "T"] & {(\Omega',\mathscr{F}')} \arrow[d, "f"] \\
& {(\mathbb{R}^1,\mathscr{R}^{1})}       
\end{tikzcd}
\end{document}
