如何根據同一行的節點設定tikz節點的寬度

我想創建以下 tikzpicture：

我現在所擁有的都是這樣的：

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{tikz}
\usetikzlibrary{positioning,backgrounds}
\begin{document}
\noindent\begin{tikzpicture}[background rectangle/.style={fill=gray!25}, show background rectangle,every node/.style={inner sep=0pt,outer sep=0pt,draw}]

\begin{scope}[local bounding box=scope1]
\path[use as bounding box] (0,0) rectangle (.5\textwidth,0);
\filldraw (0,0) circle (2pt); 
\node [text width=0.5\textwidth, align=left,anchor=north west](n1) {scope 1, node 1};
\node [below = 0pt of n1.south west,anchor=north west] (n2) {scope 1, node 2};
\node [below left = 0pt and 0pt of n2.north east,anchor=north west,align=left,text width=5.1cm] (n3) {scope 1, node 3 that includes longer text to be broken into lines};
\end{scope}

\begin{scope}[shift={(scope1.north east)},anchor=north west]
\node [text width=0.5\textwidth, align=left](n1) {scope 2, node 1};
\node [below = 0pt of n1.south west,anchor=north west] (n2) {scope 2, node 2};
\node [below left = 0pt and 0pt of n2.north east,anchor=north west,align=left,text width=5.1cm] (n3) {scope 2, node 3 which also includes longer text to be broken into lines};
\end{scope}

\end{tikzpicture}

我需要兩件事的幫助：

  1. 如何定義節點的寬度，以便和n3的總寬度是（即）的寬度？目前我將其設置為 5.1 厘米，因為它看起來不錯，但如果我更改節點 2 的內容，那麼節點 3 的尺寸也應該更改。如何利用為第一個範圍所建立的邊界框？n2n3n1.5\textwidth

  2. 如何在兩個範圍之間插入分隔符號（例如第一張圖中用黃色繪製的分隔符號）？為什麼兩個瞄準鏡的寬度超出了textwidth？雖然左右有灰邊outer sep=0pt。

答案1

背景矩形有一個填充（稱為），因此它顯示的灰色比實際內容更多。使用inner frame [xy]septight background改變這一點。
此外，線寬（任何路徑的線寬，不僅是節點的線寬，無論任何外部的sep）都會影響圖片的最終邊界框，這也會稍微影響圖片的最終位置（並會導致過度的水平盒） 。
在原始設定中，您可以使用 覆蓋邊界框的水平測量值trim left=0pt, trim right=\textwidth。在下面的程式碼中，我使用它是±.5\textwidth因為我創建了以原點為中心的圖片。

為了創建具有與其他節點相關的大小的節點，它們是fit透過設定文本寬度/高度/深度來工作的庫，如果您希望節點實際具有文本，那麼這是不好的。

我的ext.positioning-plus庫使用該庫執行類似的操作fit，但透過使用來控制新節點的大小minimum width，minimum height這對於在節點中包含文字更好，但對於比節點適合的文本長的文本需要一些工作。

我在這裡使用一個非常基本的text width between鍵，它使用calc庫來測量物件中兩個任意點之間的距離X維度並使用它來設定text width節點的 。我們需要inner xsep在這裡減去兩次（這樣最終的節點實際上覆蓋了該區域和內部 xsep)。這基本上是一種設定方法固定寬度而不是最小寬度。 （對於其他形狀，係數 2 有所不同。）

為了同步節點的大小，我可以提供ext.node-families圖書館我的tikz-ext包裹。

每個已設定的節點node family={height=row1}共享相同的minimum height.這將使每個節點中的文字垂直居中對齊。

藍色節點和黃色分隔符號（也是一個節點）將跨越相同的垂直空間。

預設情況下，使用tcbraster(或tcbitemize) fromtcolorbox , we can leave the package to do all the work for us. Theraster use\texwidth` ，每個柵格列都具有相等的寬度，但也可以手動調整它們。

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage[most]{tcolorbox}

\begin{document}

\begin{tcbitemize}[raster every box/.style={sharp corners,  
    fontupper=\sffamily, colupper=white, boxrule=0pt, halign=center},
    raster left skip=0pt, raster right skip=0pt, 
    raster before skip=0pt, raster row skip=0pt, 
    raster after skip=0pt, raster valign=top]
    \tcbitem[colback=blue!90!black] scope 1, node 1
    \tcbitem[colback=blue!90!black] scope 2, node 1
    \tcbitem[blankest, raster column skip=0pt]
        \begin{tcbitemize}[raster force size=false]
            \tcbitem[colback=red!90!black, width=.4\linewidth] scope 1, node 2
            \tcbitem[colback=green!90!black, width=.6\linewidth] scope 1, node 3 that includes longer text to be broken into lines
        \end{tcbitemize}
    \tcbitem[blankest, raster column skip=0pt]
        \begin{tcbitemize}[raster force size=false]
            \tcbitem[colback=red!90!black, width=.4\linewidth] scope 2, node 2
            \tcbitem[colback=green!90!black, width=.6\linewidth] scope 2, node 3 which also includes longer text to be broken into lines
        \end{tcbitemize}

我試圖接近您的初始代碼。但有一個問題沒有考慮：如果右上節點的高度大於左上節點的高度會發生什麼事。解決方案可能是反轉構造並以右上節點作為參考。

程式碼

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{lipsum}
\usepackage{tikz}
\usetikzlibrary{calc, positioning}

\begin{document}

\lipsum[1]
\bigskip

\tikzset{%
  T/.style={blue!50!black, fill=blue!50!black, text=white,
    minimum width=0.48\textwidth, text width=0.48\textwidth-1ex
  },
  BW/.style={green!50!black, fill=green!70!black, text=black,
    minimum width=0.17\textwidth, text width=0.17\textwidth-1ex
  },
  BE/.style={red!75!black, fill=red!95!black, text=black,
    minimum width=0.30\textwidth, text width=0.30\textwidth-1ex,
  }
}
\noindent\begin{tikzpicture}[%
  every node/.style={draw, inner sep=1ex, outer sep=0pt, align=center,
  minimum height=7ex}
  ]
  \node[T, anchor=north west] at (0, 0)
  (nTW) {\bfseries \lipsum[2]};
  \node[BW, below=0pt of nTW.south west, anchor=north west]
  (n2) {scope 1, node 2};
  \node[BE, below left=0pt and 0pt of n2.north east, anchor=north west]
  (n3) {scope 1, node 3 that includes longer text to be broken into lines};

  \path ($(nTW.south) -(nTW.north)$);
  \pgfgetlastxy{\newW}{\newH}

  \node[T, right=.02\textwidth of nTW.north east,
  anchor=north west, minimum height={-\newH}]
  (nTE) {\bfseries scope 2, node 1};
  \node[BW, below=0pt of nTE.south west, anchor=north west]
  (n2E) {scope 2, node 2};
  \node[BE, below left=0pt and 0pt of n2E.north east, anchor=north west]
  (n3E) {scope 2, node 3 that includes longer text to be broken
    into lines; can be longer than the West corresponding node};

  \fill[yellow!90!red] (nTW.north east) rectangle (nTE.south west);
\end{tikzpicture}

替代建議。我的程式碼技術性較差（但也許也不太優雅？）。

您可以調整黃色分隔符的寬度（\yellowGap在我的程式碼中），以及節點 1 的寬度百分比（percentAmount0 到 100 之間的整數，但最好不要選擇太接近 0 或 100 的值，以避免非常窄列） ，取得節點2的寬度。

最後，您可以調整節點中內部 sep 的長度\innerXSep。

\documentclass[a4paper,10pt]{article}
\usepackage[showframe]{geometry}
\usepackage[x11names]{xcolor}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{calc}

\newlength{\yellowGap}
\setlength{\yellowGap}{3mm}
\newcounter{percentAmount}
\setcounter{percentAmount}{40}% =40% of the width of the first node. Value needs to be integer
\newlength{\innerXSep}
\setlength{\innerXSep}{.3333em}% default value

\newlength{\mainNodeWidth}
\setlength{\mainNodeWidth}{(\textwidth-\yellowGap)/2}
\newlength{\secondNodeWidth}
\setlength{\secondNodeWidth}{\mainNodeWidth*\value{percentAmount}/100}
\newlength{\thirdNodeWidth}
\setlength{\thirdNodeWidth}{\mainNodeWidth-\secondNodeWidth}

\begin{document}

\noindent\begin{tikzpicture}[outer sep=0pt,inner xsep=\innerXSep,text=white]
    \node[text width=\mainNodeWidth-2\innerXSep,fill=DodgerBlue3,align=center]  (mainLeft) {Scope 1, Node 1};
    \node[text width=\secondNodeWidth-2\innerXSep,fill=Firebrick2,align=center,anchor=north west] (secondLeft) at (mainLeft.south west) {Scope 1,\\Node 2};
    \node[text width=\thirdNodeWidth-2\innerXSep,fill=Green3,align=center,anchor=north west] (thirdLeft) at (secondLeft.north east) {Scope 1, Node 3\\ that includes longer text to be broken into lines};
    \fill[DarkGoldenrod1] (mainLeft.north east) rectangle ($(mainLeft.south east)+(\yellowGap,0)$);
    \node[text width=\mainNodeWidth-2\innerXSep,fill=DodgerBlue3,align=center,anchor=north west]    (mainRight) at ($(mainLeft.north east)+(\yellowGap,0)$) {Scope 2, Node 1};
    \node[text width=\secondNodeWidth-2\innerXSep,fill=Firebrick2,align=center,anchor=north west] (secondRight) at (mainRight.south west) {Scope 2,\\Node 2};
    \node[text width=\thirdNodeWidth-2\innerXSep,fill=Green3,align=center,anchor=north west] at (secondRight.north east) {Scope 2, Node 3\\ which also includes longer text to be broken into lines};
