tikz 水平移动节点

我有以下代码，

\documentclass{article}

\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\begin{document}
\pagestyle{empty}

\definecolor{cloral}{RGB}{230, 110, 108}
\definecolor{conv}{RGB}{148, 183, 247}
\definecolor{layers}{RGB}{108, 230, 149}
% Define block styles

\tikzstyle{block} = [rectangle, draw, fill=blue!20, 
    text width=8em, text centered, rounded corners, minimum height=4em, minimum width=10em]
\tikzstyle{line} = [draw, -latex']


\begin{tikzpicture}[node distance = 4cm, auto]
    % Place nodes
    \node [block]  (init)[fill=layers, xshift=-10, minimum width=12em] {\hspace{-1em}Filter concatenation};
    \node [block, below of=init, fill=conv] (oneconv) {1X1 convolutions};
    \node [block, right of=oneconv, fill=conv] (threeconv) {3X3 convolutions};
    \node [block, right of=threeconv, fill=conv] (fiveconv) {5X5 convolutions};
    \node [block, right of=fiveconv, fill=cloral] (maxpooling) {3X3 max pooling};

    \node [block, below of=threeconv, fill=layers] (prev) {Previous Layer};
    % Draw edges
    \path [line] (oneconv) -- (init);
    \path [line] (threeconv) -- (init);
    \path [line] (fiveconv) -- (init);
    \path [line] (maxpooling) -- (init);
    \path [line] (prev) -- (oneconv);
    \path [line] (prev) -- (threeconv);
    \path [line] (prev) -- (fiveconv);
    \path [line] (prev) -- (maxpooling);
\end{tikzpicture}


\end{document}

基本上，我只想移动第一个节点，使其位于流程图的中间。我试过使用，xshift但似乎没有任何区别。

答案1

我没有将 4 个中间节点相对于顶部节点进行定位，而是将顶部节点和底部节点相对于这 4 个节点的中心进行定位。

为此，我创建了一个位于两个节点中间的辅助节点 (aux)(threeconv)并(fiveconv)使用该calc库。

\node (aux) at ($(threeconv)!.5!(fiveconv)$){};
\node [block,above of=aux]  (init)[fill=layers, minimum width=12em] {\hspace{-1em}Filter concatenation};

\node [block, below of=aux, fill=layers] (prev) {Previous Layer};

您无需加载任何额外的库，也无需进行复杂的计算。您需要做的就是将四个节点放在矩阵的中间。（顺便说一句，\tikzstyle已弃用，您可以在循环中绘制箭头。）

\documentclass[tikz,border=3mm]{standalone}    
\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\begin{document}
\pagestyle{empty}

\definecolor{cloral}{RGB}{230, 110, 108}
\definecolor{conv}{RGB}{148, 183, 247}
\definecolor{layers}{RGB}{108, 230, 149}
% Define block styles

\tikzset{block/.style={rectangle, draw, fill=blue!20, 
    text width=8em, text centered, rounded corners, minimum height=4em, minimum
    width=10em},
line/.style={draw, -latex'}}


\begin{tikzpicture}[node distance = 4cm, auto]
    % Place nodes
    \node [block]  (init)[fill=layers, xshift=-10, minimum width=12em] {\hspace{-1em}Filter concatenation};
    \matrix[below of=init,column sep=1em] (mat){
    \node [block,  fill=conv] (oneconv) {1X1 convolutions}; &
    \node [block, fill=conv] (threeconv) {3X3 convolutions}; &
    \node [block,  fill=conv] (fiveconv) {5X5 convolutions}; &
    \node [block, fill=cloral] (maxpooling) {3X3 max pooling};\\
    };

    \node [block, below of=mat, fill=layers] (prev) {Previous Layer};
    % Draw edges
    \path [line] (oneconv) -- (init);
    \path [line] (threeconv) -- (init);
    \path [line] (fiveconv) -- (init);
    \path [line] (maxpooling) -- (init);
    \path [line] (prev) -- (oneconv);
    \path [line] (prev) -- (threeconv);
    \path [line] (prev) -- (fiveconv);
    \path [line] (prev) -- (maxpooling);
\end{tikzpicture}

通过使用 TikZ 库calc并chains在循环中绘制连接线，您的代码会变得更短更清晰：

\documentclass[tikz, border=3mm]{standalone}
\usetikzlibrary{arrows.meta,
                calc, chains,
                positioning}

\definecolor{cloral}{RGB}{230, 110, 108}
\definecolor{conv}{RGB}{148, 183, 247}
\definecolor{layers}{RGB}{108, 230, 149}

\begin{document}
    \begin{tikzpicture}[
node distance = 17mm and 2mm,
  start chain = A going right,
box/.style = {rectangle, rounded corners, draw, fill=#1,
              minimum width=9em, minimum height=6ex, align=center,
              on chain=A},
box/.default = conv,
arr/.style = {-Latex}
                        ]
% Place nodes
% midle row
\node   [box]  {$1 \times 1$ convolutions};
\node   [box]  {$3 \times 3$ convolutions};
\node   [box]  {$5 \times 5$ convolutions};
\node   [box=cloral]{$3 \times 3$ max pooling};
% top
\node   [box= green!30,
         above=of $(A-1.north)!0.5!(A-4.north)$]    {Filter concatenation};
% bottom
\node   [box= green!30,
         below=of $(A-1.south)!0.5!(A-4.south)$]    {Previous Layer};
% Draw edges
\foreach \i in {1,...,4}
{
\draw[arr]  (A-\i) -- (A-5);
\draw[arr]  (A-6) -- (A-\i);
}
    \end{tikzpicture}
\end{document}

绘制方式：

  • 首先绘制具有名称的节点链A-1，...A-4使用chains库
  • 节点链中间的上方是定位顶部节点，使用calc和positioning库顶部节点
  • 类似地，顶部节点添加到底部节点
  • 连接线在循环中绘制。其中利用了节点的命名A-1、A-2等。
  • 在节点和箭头样式的定义中，样式在选项中移动ikzpicture，并使用最近的样式语法（˙\tikzstyle` 已过时）

答案4

所有其他节点都相对于第一个节点放置init。因此更改它不会产生任何影响。xshift最左边的节点oneconv将获得中心对齐的第一个节点。
