将 2 个 \foreach 循环放置在 2 个不同的位置

Question

使用以下代码从答案这个问题

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{verbatim}
\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{positioning, chains}
\begin{document}
\begin{frame}[fragile, t]
\frametitle{}
\begin{tikzpicture}[scale=.8, transform shape,
node distance = 1mm and 60mm,
  start chain = going below,
   boxa/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=7.1mm,
             inner sep=0pt, outer sep=0.96mm,
             on chain},
   boxb/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=7.1mm,
             inner sep=0pt, outer sep=0.96mm,
             on chain},
   boxc/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=12.7mm,
             inner sep=0pt, outer sep=0.6mm,
             on chain},
]
\draw [line width=.4mm, black, dashed] (0,5.8) -- +(0:11) (0,0) -- +(0:11) node [pos=.28] (B) {\Large B} node [pos=.68] (A) {\Large A};

\node at ([shift={(90:5.4cm)}]A.center) (n1) [boxa=blue!60!white] {};
\node (n2) [boxa=blue!60!white] {};
\foreach \i in {3,...,6}
\node (n\i) [boxb=red!60!white] {};
\foreach \i in {0,...,3}
\node at ([shift={(90:5.4cm)}]B.center) (n\i) [boxc=green!60!white] {};
\end{tikzpicture}
\vskip -9.45cm
\hskip 2.22cm
\begin{tikzpicture}[scale=.8, transform shape,
node distance = 1mm and 60mm,
  start chain = going below,
   boxc/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=12.7mm,
             inner sep=0pt, outer sep=0.6mm,
             on chain},
]
\foreach \i in {0,...,3}
\node (n\i) [boxc=violet!60!white] {};
\end{tikzpicture}
\end{frame}
\end{document}

我想将绿色框定位在 B 节点的位置。我使用了代码

    \foreach \i in {0,...,3}
\node at ([shift={(90:5.4cm)}]B.center) (n\i) [boxc=green!60!white] {};

但这不起作用。该怎么做呢？

我不知道如何正确定位它们。我不得不手动操作，就像我对另一张 tikzpicture 中的紫色框所做的那样。

我刚刚意识到你的问题...你的问题是你已经用选项定义了这种风格on chain...我在第三个相同风格的名称上删除了它boxd，结果如下：

\documentclass{article}
\usepackage{verbatim}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.15}
\usetikzlibrary{positioning, chains}
\begin{document}
\begin{tikzpicture}[scale=.8, transform shape,
node distance = 1mm and 60mm,
  start chain = going below,
   boxa/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=7.1mm,
             inner sep=0pt, outer sep=0.96mm,
             on chain},
   boxb/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=7.1mm,
             inner sep=0pt, outer sep=0.96mm,
             on chain},
   boxc/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=12.7mm,
             inner sep=0pt, outer sep=0.6mm,
             on chain},
   boxd/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=12.7mm,
             inner sep=0pt, outer sep=0.6mm},
]
\draw [line width=.4mm, black, dashed] (0,5.8) -- +(0:11) (0,0) -- +(0:11) node [pos=.28] (B) {\Large B} node [pos=.68] (A) {\Large A};

\node at ([shift={(90:5.4cm)}]A.center) (n1) [boxa=blue!60!white] {};
\node (n2) [boxa=blue!60!white] {};
\foreach \i in {3,...,6}
\node (n\i) [boxb=red!60!white] {};
\foreach \i in {0,...,3}
\node at ([shift={(90:5.4cm)}]B.center) (n\i) [boxc=green!60!white] {};
\foreach \i in {0,...,3}
\node (l\i)at ($(0,-0.75)+({0.28*11},{-\i*1.5})$)  [boxd=green!60!white] {};
\end{tikzpicture}
\end{document}
