Tikz 在线的另一侧添加文本

Question

我有以下代码，可在绘制的每一行左侧添加文本。如何使文本显示在右侧？谢谢。

\begin{center}
    \begin{tikzpicture}[auto]
        \node (Q1) at (1,1) {\(\mathbb{Q}\)};
        \node (Q2) at (1,3) {\(\mathbb{Q}(\sqrt[3]{2})\)};
        \node (Q3) at (1,5) {\(\mathbb{Q}(\sqrt[3]{2},\alpha)\)};
        \draw[-] (Q1) to node {basis\(\{1,\sqrt[3]{2},(\sqrt[3]{2})^2\}\)} (Q2);
        \draw[-] (Q2) to node {basis\(\{1,\alpha\}\)} (Q3);
    \end{tikzpicture} 
\end{center}

Answer 1

您可以将其用作[right]节点的选项。此外，=distance您还可以精确设置到线的距离：

\documentclass{article}

\usepackage{tikz}
\usepackage{amssymb}

\begin{document}
    \begin{center}
        \begin{tikzpicture}[auto]
            \node (Q1) at (1,1) {\(\mathbb{Q}\)};
            \node (Q2) at (1,3) {\(\mathbb{Q}(\sqrt[3]{2})\)};
            \node (Q3) at (1,5) {\(\mathbb{Q}(\sqrt[3]{2},\alpha)\)};
            \draw[-] (Q1) to node[right=0.2cm] {basis\(\{1,\sqrt[3]{2},(\sqrt[3]{2})^2\}\)} (Q2);
            \draw[-] (Q2) to node[right=0.2cm] {basis\(\{1,\alpha\}\)} (Q3);
        \end{tikzpicture} 
    \end{center}
\end{document}
