如何定义节点之间的默认垂直距离？

使用positioning可以控制节点的单独垂直位置。但是有没有什么方法可以控制默认的垂直间距呢？

\usepackage[utf8]{输入框}
\usepackage{tikz}
\usetikzlibrary{形状，箭头，定位}

\开始{文档}
\pagestyle{空}

\tikzstyle{decision} = [diamond, draw, 文本宽度=4.5em, 文本居中严重, 节点距离=3.5cm, 内部分离=0pt]
\tikzstyle{block} = [矩形，绘制，文本宽度=6em，文本居中，圆角，最小高度=4em，节点距离=3.5cm，最小高度=2em]
\tikzstyle{cloud} = [绘制，椭圆，节点距离=3.5cm，最小高度=2em]
\tikzstyle{线} = [绘制，-latex']

\begin{tikzpicture}[节点距离 = 1cm，自动]
  \node [块] (第 1 个) {第 1 个}；
  \node [block, 右边=1st] (2nd1) {2nd1};
  \node [block, 距 2nd1 0.7cm 以上] (2nd2) {2nd2};
  \node [block, 下方=2nd1] (2nd3) {2nd3};
  \node [block, 右边=2nd1] (3rd1) {3rd1};
  \node [block, 上方=3rd1] (3rd2) {3rd2};
  \node [block, 上方=3rd2] (3rd3) {3rd3};
  \node [block, 下方=3rd1] (3rd4) {3rd4};
  \node [block, 低于=3rd4] (3rd5) {3rd5};

  \path [行] (第一行) -- (第二行1)；
  \path [行] (2nd1) -- (2nd2);
  \path [行] (2nd1) -- (2nd3);
  \path [行] (2nd2) -- (3rd3);
  \path [行] (第二行1) -- (第三行1);
  \path [行] (第一行) -- (第二行1)；
\结束{tikzpicture}

像这样。我改变了垂直位置，2nd2但其他的保持不变。我是否必须为每个节点添加单独的垂直间距控制？

答案1

您可以通过输入以下代码来更改默认值：

\tikzset{node distance = 1cm and 2cm}

其中第一个参数是垂直节点距离，第二个参数是水平节点距离。如果只输入一个参数，则垂直和水平节点距离都将设置为该值。

作为特里克斯在评论中指出，在节点属性中，使用类似的above= of 2nd1而不是above of= 2nd1。

答案2

我不太明白这个问题，所以我希望这是你想要的。如果你附上一份完整的文档（这样我们就可以复制粘贴并在系统上看到问题），事情就会简单得多。

在这里，您可以在一定范围内更改默认设置，但您的block样式node distance每次发布时都会重置。我将其设置为 2mm，以便我们更容易看到差异。

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}
