Tikz，箭头格式

Tikz，箭头格式

考虑下面的图片： 在此处输入图片描述

以及底部的代码。我对左边的结果很满意；现在我已经开始使用二合字母，我需要箭头；我正在尝试获得对我来说最好的风格。我想实现以下目标：

  1. 箭头与子弹应有 1pt 的间距，但箭头尾部不应有间隙，当然正常边缘也不应有间隙
  2. [完成] 头部应该像下面这个样子（而不是像我尝试的那样是三角形）： pgfplots：自定义轴箭头
  3. [完成] 并且标准头部不应该出现
  4. 由于我用python生成了图片，箭头的格式应该封装在样式中，正如我对具有样式的节点所做的那样bullet，请参阅我的尝试myarrow

。

答案1

您应该myarrow/.style在第一个方括号内包含以定义样式。在样式中，您可以使用选项指定箭头尖端与节点的距离，sep=1pt如下例所示。

如果myarrow要在多个环境中使用该样式tikzpicture，则可以在序言中定义该样式，而\tikzset{myarrow/.style={...}}不是在每个单独的环境的可选参数中定义它。

答案2

用于regular polygon确定项目符号的坐标（dot在下面的 MWE 中命名）和用于在子图 b 中绘制线条的循环。箭头和节点形状的样式对于两张图片都是通用的。箭头定义为

arr/.style = {-{Stealth[length=2mm, width=2mm]},shorten >=1pt},

答案3

您可以使用缩短 > 作为选项或样式。 在此处输入图片描述

\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}
\foreach \i in {0,...,5}
\fill (60*\i:2) circle(2pt) coordinate (A\i); 

\draw (A0)--(A1)--(A2)--(A3)--(A4);
\draw[-stealth, shorten >=3pt] (A4)--(A5);
\draw[-stealth, shorten >=3pt] (A5)--(A0);
\end{tikzpicture}

\begin{tikzpicture}[myarr/.style={-stealth, shorten >=3pt}]
\foreach \i in {0,...,5}
\fill (60*\i:2) circle(2pt) coordinate (A\i); 

\draw (A0)--(A1)--(A2)--(A3)--(A4);
\draw[myarr] (A4)--(A5);
\draw[myarr] (A5)--(A0);
\end{tikzpicture}
\end{document}
