线条粗细不可控制 tikz

线条粗细不可控制 tikz

我使用下面的代码，我不明白为什么“水平线”比其他的更细。

在此处输入图片描述

\documentclass{article}

\usepackage{tikz,tikz-3dplot}
\usetikzlibrary{calc,arrows,positioning}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}

\begin{document}

\begin{tikzpicture}[scale=5,
  vector/.style={thick,black,>=stealth,->},
  atom/.style={blue}
  ]
  \begin{axis}[
    axis lines=none,
    xmin=-0.1,
    xmax=2.1,
    ymin=-0.1,
    ymax=2.1,
    zmin=-0.1,
    zmax=2.1,
   % xtick=\empty,
  %  ytick=\empty,
  %  ztick=\empty
    ]        
    \coordinate (A0) at (axis cs:0,0,0);
    \coordinate (A1) at (axis cs:0.2,0.5,0);
    \coordinate (A2) at (axis cs:0.6,0.4,0);
    \coordinate (A3) at (axis cs:0.8,0.9,0);
     \coordinate (A4) at (axis cs:0.2,0,1);
    \coordinate (A5) at (axis cs:0.4,0.5,1);
    \coordinate (A6) at (axis cs:0.8,0.4,1);
    \coordinate (A7) at (axis cs:1,0.9,1);

    \draw[blue] (A0) -- (A1) -- (A5) -- (A4) -- cycle;
    \draw[blue] (A2) -- (A3) -- (A7) -- (A6) -- cycle;
    \draw[blue] (A0) -- (A1) -- (A3) -- (A2) -- cycle;
    \draw[blue] (A4) -- (A5) -- (A7) -- (A6) -- cycle;    
     \draw[vector,red] (A0) -- (A4);
    \end{axis}
\end{tikzpicture}
\end{document}

代码中的行

vector/.style={thick,black,>=stealth,->},

仅有的定义vector包含选项的样式。thick这只是样式的定义vector，并不适用于任何地方。红线由

\draw[vector,red] (A0) -- (A4);

它应用了vector样式和，因此红线为thick。其他蓝线均使用\draw[blue] ...不包含线条粗细规范的样式绘制，因此这些线条为默认粗细。

如果你想要相同的厚度，你可以用

\draw[vector,blue] ...

或者，您可以使用scope并将样式应用于vector该scope。

笔记：

  • 我还添加了line join=round以获得更好的图像。

代码：

\documentclass{article}

\usepackage{tikz,tikz-3dplot}
\usetikzlibrary{calc,arrows,positioning}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}

\begin{document}

\begin{tikzpicture}[scale=5,
  vector/.style={thick,black,>=stealth,->},
  atom/.style={blue}
  ]
  \begin{axis}[
    axis lines=none,
    xmin=-0.1,
    xmax=2.1,
    ymin=-0.1,
    ymax=2.1,
    zmin=-0.1,
    zmax=2.1,
    %xtick=\empty,
    %ytick=\empty,
    %ztick=\empty
    ]        
    \coordinate (A0) at (axis cs:0,0,0);
    \coordinate (A1) at (axis cs:0.2,0.5,0);
    \coordinate (A2) at (axis cs:0.6,0.4,0);
    \coordinate (A3) at (axis cs:0.8,0.9,0);
    \coordinate (A4) at (axis cs:0.2,0,1);
    \coordinate (A5) at (axis cs:0.4,0.5,1);
    \coordinate (A6) at (axis cs:0.8,0.4,1);
    \coordinate (A7) at (axis cs:1,0.9,1);

    \begin{scope}[vector, line join=round]
        \draw [blue] (A0) -- (A1) -- (A5) -- (A4) -- cycle;
        \draw [blue] (A2) -- (A3) -- (A7) -- (A6) -- cycle;
        \draw [blue] (A0) -- (A1) -- (A3) -- (A2) -- cycle;
        \draw [blue] (A4) -- (A5) -- (A7) -- (A6) -- cycle;    
        \draw [red]  (A0) -- (A4);
    \end{scope}
    \end{axis}
\end{tikzpicture}
\end{document}
