TikZ 定位：沿底部边缘对齐节点

Question

我有以下代码：

\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath,amsfonts,physics}
\usetikzlibrary{shapes.multipart,positioning}
\begin{document}
\begin{tikzpicture}[stack/.style={rectangle split, rectangle split parts=#1, draw, anchor=south},auto]
    \node (LMA) [stack=1,label=below:{\texttt{LM(A)}}] {
        \nodepart{one}\(\vb*{A}\)
    };
    \node (PUM1) [stack=2,label=below:{\texttt{PuM()}},right=of LMA] {
        \nodepart{one}\(\vb*{A}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (MMB) [stack=2,label=below:{\texttt{MM(B)}},right=of PUM1] {
        \nodepart{one}\(\vb*{AB}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (MMC) [stack=2,label=below:{\texttt{MM(C)}},right=of MMB] {
        \nodepart{one}\(\vb*{ABC}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (LMD) [stack=2,label=below:{\texttt{LM(D)}},right=of MMC] {
        \nodepart{one}\(\vb*{D}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (PUM2) [stack=3,label=below:{\texttt{PuM()}},right=of LMD] {
        \nodepart{one}\(\vb*{D}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
    \node (MME) [stack=3,label=below:{\texttt{MM(E)}},right=of PUM2] {
        \nodepart{one}\(\vb*{DE}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
    \node (MMF) [stack=3,label=below:{\texttt{MM(F)}},right=of MME] {
        \nodepart{one}\(\vb*{DEF}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
\end{tikzpicture}
\end{document}

生成以下内容：

我该如何改变它，使所有的堆栈都沿着它们的底部边缘来显示矩阵堆栈的增长（我已经尝试过这个anchor=south，但显然不起作用），标签紧挨着下面？

Answer 1

使用以下选项定位与前一个节点大小不同的两个节点

right=of LMA.south east,anchor=south west
right=of LMD.south east,anchor=south west

分别。

\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath,amsfonts,physics}
\usetikzlibrary{shapes.multipart,positioning}
\begin{document}
\begin{tikzpicture}[stack/.style={rectangle split, rectangle split parts=#1, draw, anchor=south},auto]
    \node (LMA) [stack=1,label=below:{\texttt{LM(A)}}] {
        \nodepart{one}\(\vb*{A}\)
    };
    \node (PUM1) [stack=2,label=below:{\texttt{PuM()}},right=of LMA.south east,anchor=south west] {
        \nodepart{one}\(\vb*{A}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (MMB) [stack=2,label=below:{\texttt{MM(B)}},right=of PUM1] {
        \nodepart{one}\(\vb*{AB}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (MMC) [stack=2,label=below:{\texttt{MM(C)}},right=of MMB] {
        \nodepart{one}\(\vb*{ABC}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (LMD) [stack=2,label=below:{\texttt{LM(D)}},right=of MMC] {
        \nodepart{one}\(\vb*{D}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (PUM2) [stack=3,label=below:{\texttt{PuM()}},right=of LMD.south east,anchor=south west] {
        \nodepart{one}\(\vb*{D}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
    \node (MME) [stack=3,label=below:{\texttt{MM(E)}},right=of PUM2] {
        \nodepart{one}\(\vb*{DE}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
    \node (MMF) [stack=3,label=below:{\texttt{MM(F)}},right=of MME] {
        \nodepart{one}\(\vb*{DEF}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
\end{tikzpicture}
\end{document}

Answer 2

改编

• （我稍微降低了 MWE）
• 用于anchor=south west所有节点（仅当您给出位置时才考虑锚点，例如at (x, y)或节点的位置（参见gernots 回答)，不是节点）
• 将位置设置为south east最后一个节点加上偏移量，定义在 中dist。

代码

\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath,amsfonts,physics}
\usetikzlibrary{shapes.multipart,positioning}

\begin{document}
\begin{tikzpicture}[
    stack/.style={rectangle split, rectangle split parts=#1, draw, anchor=south west},
    auto,
    dist/.style={xshift=10mm}
    ]
    
    \node (LMA) [stack=1,label=below:{\texttt{LM(A)}}] {
        \nodepart{one}\(\vb*{A}\)
    };
    \node (PUM1) [stack=2,label=below:{\texttt{PuM()}}] at ([dist] LMA.south east) {
        \nodepart{one}\(\vb*{A}\)
        \nodepart{two}\(\vb*{A}\)
    };
    \node (PUM2) [stack=3,label=below:{\texttt{PuM()}}] at ([dist] PUM1.south east) {
        \nodepart{one}\(\vb*{D}\)
        \nodepart{two}\(\vb*{D}\)
        \nodepart{three}\(\vb*{A}\)
    };
\end{tikzpicture}
\end{document}

结果
