TikZ - 将两个绘图放在相同的 TikZ 环境和垂直间距中

在下面的代码中，我想将两个列表显示在同一个环境中，并以一个垂直指定的间距显示。

我怎样才能做到这一点 ？

代码

\documentclass{article}
    \usepackage{tikz}
    \usepackage{xstring}

    \tikzset{
        raw sort entry/.style={rectangle, thick, draw, node distance=1.5em},
        sort entry black/.style={raw sort entry, black, fill=white},
        sort entry blackgray/.style={raw sort entry, black, fill=gray!25},
        s1/.style={raw sort entry, red, fill=yellow!30},
        s2/.style={raw sort entry, blue, fill=green!20},
        s3/.style={raw sort entry, violet, fill=orange!25}
    }

    \newcommand*{\List}[2][sort entry black]{%
      \par\noindent%
      \edef\listtoprocess{#2}%
      \def\ListToProcess{}%
      \begin{tikzpicture}[inner sep=2pt, outer sep=0]
        \foreach \content in \listtoprocess{
          \IfSubStr{\content}{/}{% true
            \xdef\ListToProcess{\ListToProcess,\content}
          }{%                      false
            \xdef\ListToProcess{\ListToProcess,#1/\content}
          }
        }
        \StrGobbleLeft{\ListToProcess}{1}[\ListToProcess]% removes the first comma (\listToProcess is empty at the start)
        \foreach [count=\i] \Style/\Value in \ListToProcess {
          \ifnum\i=1\relax
            \node [raw sort entry, \Style] (sortnode\i) {\Value};
          \else
            \node [raw sort entry, right of=sortnode\number\numexpr\i-1\relax, \Style] (sortnode\i) {\Value};
          \fi
        }
      \end{tikzpicture}%
    }

\begin{document}

\List[sort entry blackgray]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}

\bigskip

\List[sort entry blackgray]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}

\end{document}

答案1

我只是重复使用代码TikZ 箭头用于显示排序算法并添加了键

  • previous row和
  • previous col

我用库提供的right of=…语法替换了旧语法。（→right=… of …positioningPGF/TikZ 中“right of=”和“right=of”之间的区别)
值.5em(水平) 和1em(垂直) 在宏中是硬编码的\List。

previous row在处理一行中的所有节点结束时，键会自动设置为当前行名，以便在下面的\List调用中previous row已经设置为前一行名（参见第一个示例）。

使用上述按键可以进行手动放置。参见第二个示例（previous row=a实际上并不需要，但为了完整性还是添加了）。
