图片定位

Question

我想画两张图片，第二张图片应该在第一张图片下面。这是我目前的情况：

第二张图片如何能获得与第一张图片相同的 x 坐标？

代码：

\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{positioning}
\usetikzlibrary{fit}
\begin{document}

\tikzset{
    pics/vhsplit/.style n args = {3}{
        code = {
        \node (A) at (0,0) {#1};
        \node[anchor=south west] (B) at (A.east) {#2};
        \node[anchor=north west] (C) at (A.east) {#3};
        \node[inner sep=0pt, outer sep=0pt, draw, rounded corners, fit=(A)(B)(C)] (-box) {}; 
        \draw (B.north west) -- (C.south west)
              (B.south west) -- (C.north east);
        }
    }
}

\begin{tikzpicture}
\pic (a) {vhsplit={a}{2.0}{6.0}};
\pic[below=10mm of a-box.south] (b) {vhsplit={b}{-3.0}{-4.0}};
\end{tikzpicture}

\end{document}

Answer 1

图片不像节点那么智能。图片的原点总是被放置在指定的位置。

tabular如果这就是您所需要的，那么使用节点内部带有 的普通节点可能会更容易 。以下是三种方法：

1. 普通文本和两行一列的表格
   →vhsplit
2. 一个有两行两列的表格，#1放在\multirow
   →vhsplit'
3. Arectangle split形状来自shapes.multipart图书馆，同样使用表格形式，如 1 所示。
   →vhsplit''

由于表格的线需要接触节点的边框，我将 s inner sep（默认 .3333em）设置为零，然后再次在适当的位置插入该空格。

左侧部分的垂直位置有点多变，请选择最适合您用例的位置（解决方案按此顺序用红色/绿色/蓝色表示，并用 相互叠放opacity=.3333）：

代码

\documentclass[tikz,border=2mm]{standalone}
\usepackage{hhline}
\usepackage{multirow}
\usetikzlibrary{positioning}
\tikzset{
  vhsplit/.style n args={3}{% text and a tabular
    shape=rectangle, draw, rounded corners, inner sep=+0pt,
    node contents={%
      \setlength{\tabcolsep}{.3333em}%
      \hspxsep#1\hspxsep
      \begin{tabular}{|l@{\hspxsep}}
        \vstysep$#2$\\\hhline{|-}
        \vstysep$#3$%
      \end{tabular}}},
  vhsplit'/.style n args={3}{
    shape=rectangle, draw, rounded corners, inner sep=+0pt,
    node contents={% multirow in a tabular
      \setlength{\tabcolsep}{.3333em}%
      \begin{tabular}{l|l@{\hspxsep}}
        \multirow{2}{*}{#1} &
        \vstysep$#2$\\\hhline{~|-}
        & \vstysep$#3$%
      \end{tabular}}}}
\usetikzlibrary{shapes.multipart}
\tikzset{
  vhsplit''/.style n args={3}{
    shape=rectangle split, rectangle split horizontal, rectangle split parts=2,
    draw, rounded corners, inner sep=+0pt,
    node contents={% two nodeparts and a tabular
      \hspxsep#1\hspxsep\null
      \nodepart{two}\setlength{\tabcolsep}{.3333em}%

        \vstysep$#3$
      \end{tabular}}}}
\newcommand*\hspxsep{\hspace{.3333em}}
\newcommand*\vstysep{\rule{0pt}{1.0333em}}
\begin{document}
\begin{tikzpicture}
\node             (a) [vhsplit={a}{ 2.0} {6.0}];
\node[below=of a] (b) [vhsplit={b}{-3.0}{-4.0}];

\tikzset{xshift=2cm}
\node (a)         (a) [vhsplit'={a} {2.0} {6.0}];
\node[below=of a] (b) [vhsplit'={b}{-3.0}{-4.0}];

\tikzset{xshift=2cm}
\node             (a) [vhsplit''={a} {2.0} {6.0}];
\node[below=of a] (b) [vhsplit''={b}{-3.0}{-4.0}];
\end{tikzpicture}

尝试这个：

\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{positioning}
\usetikzlibrary{fit}
\begin{document}
    
    \tikzset{
        pics/vhsplit/.style n args = {3}{
            code = {
                \node (A) at (0,0) {#1};
                \node[anchor=south west] (B) at (A.east) {#2};
                \node[anchor=north west] (C) at (A.east) {#3};
                \node[inner sep=0pt, outer sep=0pt, draw, rounded corners, fit=(A)(B)(C)] (-box) {}; 
                \draw (B.north west) -- (C.south west)
                (B.south west) -- (C.north east);
            }
        }
    }

    \begin{tikzpicture}{scale=3} % <-- changed
        \pic (a) {vhsplit={a}{2.0}{6.0}};
        \pic[xshift=0cm,yshift=-1cm] (b) {vhsplit={b}{-3.0}{-4.0}};
    \end{tikzpicture}
    
\end{document}
