有色有向图

我正在尝试使用 Tikz 在 LaTeX 中绘制下图： 在此处输入图片描述 我怎样才能实现这样的图像？

我对处理人为的“√”（勾）和“×”（叉）感到困惑。

顺便问一下，\foreach您推荐哪份 PDF 介绍？

感谢您的帮助！

谢谢大家！

现在，我可以绘制下面的图形了。（但是如何处理复选标记和其他图形的位置？） 在此处输入图片描述

据我所知，我们应该用它foreach来绘制其他图形。

代码：

\documentclass[border={10}]{standalone}
\usepackage{tikz}
\usepackage{amssymb}
\usepackage{pifont}
\usetikzlibrary{decorations.markings}
\usetikzlibrary{backgrounds,shadows,fit,positioning}
\usetikzlibrary{calc}
\newcommand{\C}{\ding{51}}
\newcommand{\X}{\ding{55}}
\begin{document}
\begin{tikzpicture}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

    markings,
    mark=between positions 0.43 and 1 step 3.14cm with {\arrow{stealth};}}
]

我不太确定这是否是正确的输出，所以请仔细看看。代码中有一些注释，如果有任何不清楚的地方可以询问。

建议的解决方案是通过 Tikz。

代码如下

\documentclass[border={10}]{standalone}
\usepackage{tikz}
\usepackage{amssymb}
\usepackage{pifont}
\usetikzlibrary{decorations.markings}
\newcommand{\C}{\ding{51}}
\newcommand{\X}{\ding{55}}

\begin{document}
\begin{tikzpicture}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
[decoration={
    markings,
    mark=between positions .4 and 1.0 step 3cm with {\arrow{stealth};}}
]
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%\node at (1.5,1.5) {(\textcolor{red}{\C})}; % for checkmark
\node at (1.5,1.5) {(\textcolor{red}{\X})}; % for crossmark
\draw[blue,thick,postaction={decorate}] (-.5, .5) circle (1cm);
\draw[orange,thick,postaction={decorate}] ( .5,-.5) circle (1cm);
\draw[fill] (.5,.5) circle (.05cm);
\draw[fill=white,draw=black] (-.5,-.5) circle (.05cm);
\end{tikzpicture}
\end{document}

稍微不必要的 TikZ 勾选和交叉：

\documentclass[border=5]{standalone}
\usepackage{tikz}
\tikzset{%
    tick/.pic={
        \draw [x=1ex, y=1ex, line width=0.25ex,
               red, line cap=round, line join=round, looseness=0.444]
          (3/2,3) to [bend right]  (0,0) to [bend right] (-1,1);
    },
    cross/.pic={
        \draw [x=1ex, y=1ex, line width=0.25ex,
               red, line cap=round, line join=round, looseness=0.444]
          (1,2) to [bend right]  (-1,0) (1, 0)  to [bend right] (-1,2);
    }
}
\def\tikztick{\tikz[baseline=0.75ex]\pic{tick};}
\def\tikzcross{\tikz[baseline=0.5ex]\pic{cross};}

\begin{document}
(\tikzcross) (\tikztick)
\end{document}
