旧代码-三个不同pic的

我有一个计划显示的 tikz 图像，然后显示一个新版本，其中突出显示一个节点，其他节点静音。我想将 SSS 和 SSI 内所有节点的填充量更改为fill=color!50。（值得一提的是，它位于一个更大的数字内，我希望这样做）。

\documentclass{standalone}
\usepackage{tikz}
\definecolor{colorS}{RGB}{0,154,128}
\definecolor{colorI}{RGB}{255,32,0}
\tikzstyle{SusCirc}=[circle,draw=black!50,fill=colorS!90,thick, minimum size=2mm]%a circle
                                %representing a susceptible individual
\tikzstyle{InfCirc}=[circle,draw=black!50,fill=colorI!90,thick, minimum size=2mm]%a circle
                                %representing an infected individual
\tikzstyle{BigCirc}=[circle,draw=black!50,thick,inner sep=0pt,minimum size=0pt]


\begin{document}
\begin{tikzpicture}
\node[BigCirc] (SSS) at (0.000000, 0.000000) {\scalebox{0.25}{\begin{tikzpicture}
  \node[SusCirc, minimum size = 8mm] (center) at (0.000000,0.000000) {};
  \node[SusCirc, minimum size = 8mm] (left) at (1.000000,0.000000) {};
  \node[SusCirc, minimum size = 8mm] (top) at (-1.000000,0.000000) {};
  \draw [-] (center) -- (left);
  \draw [-] (center) -- (top);
\end{tikzpicture}}};


\node[BigCirc] (SSI) at (2.954020, -1.762016) {\scalebox{0.25}{\begin{tikzpicture}
  \node[SusCirc, minimum size = 8mm] (center) at (0.000000,0.000000) {};
  \node[SusCirc, minimum size = 8mm] (left) at (1.000000,0.000000) {};
  \node[InfCirc, minimum size = 8mm] (top) at (-1.000000,0.000000) {};
  \draw [-] (center) -- (left);
  \draw [-] (center) -- (top);
\end{tikzpicture}}};


\node[BigCirc] (SIS) at (4.237137, -0.360863) {\scalebox{0.25}{\begin{tikzpicture}
  \node[SusCirc, minimum size = 8mm] (center) at (0.000000,0.000000) {};
  \node[InfCirc, minimum size = 8mm] (left) at (1.000000,0.000000) {};
  \node[SusCirc, minimum size = 8mm] (top) at (-1.000000,0.000000) {};
  \draw [-] (center) -- (left);
  \draw [-] (center) -- (top);
\end{tikzpicture}}};

  \draw [-] (SSS) -- (SSI);
  \draw [-] (SSS) -- (SIS);

\end{tikzpicture}
\end{document}

这是当前的外观。在此处输入图片描述（抱歉——显然防火墙阻止了我的第一次上传？？？）

如上所述：我想将 SSS 和 SSI 内所有节点的填充量更改为fill=color!50。一定有一种方法可以做到这一点，而不必编辑每个节点。

明确地说：我想编写一个命令来更改我的某个BigCircs 中所有节点的填充分数。我给出的是一个最小的工作示例，但我拥有的其中包含更多节点。

一般来说，我认为嵌套tikzpictures 是应该避免的。为此，您可以尝试定义pic，这是 TikZ 3.0 中引入的。在这种情况下，您可以轻松修改fill opacity（或只是opacity，这也会影响外圆），如下例所示。

这里我定义了一个pic接受三个参数的函数，它们是三个小圆圈的样式，第一个参数表示左边的圆圈，第二个参数表示中间的圆圈，第三个参数表示右边的圆圈。

尝试使用节点选项来确定节点突出显示的不透明度：

\documentclass[border=3mm,
               tikz]{standalone}
\usetikzlibrary{chains,fit,positioning}
    \definecolor{colorS}{RGB}{0,154,128}
    \definecolor{colorI}{RGB}{255,32,0}

\makeatletter
\tikzset{reset/.code={\def\tikz@after@path{}}}
\makeatother

\begin{document}
    \begin{tikzpicture}[
    node distance = 1mm,
      start chain = going right,
every node/.style = {draw=black!50, circle,
                     inner sep=0pt, minimum size=2mm,
                     node contents={}},
   SusCirc/.style = {fill=colorS!#1,% #1 determine color intensity 
                     join=by -, on chain},
   InfCirc/.style = {fill=colorI!#1, join=by -, on chain},
   BigCirc/.style = {very thick}
                        ]
\node (s11) [SusCirc=90];
\node (s12) [SusCirc=90];
\node (s13) [SusCirc=90];
    \node (SSS) [BigCirc,fit=(s11) (s13)];
%
\node (s21) [SusCirc=90,reset,
             below right=0mm and 55mm of SSS];
\node (s22) [SusCirc=90];
\node (s23) [InfCirc=90];
    \node (SSI) [BigCirc,fit=(s21) (s23)];
%
\node (s31) [InfCirc=50,reset,
             below right=21mm and 33mm of SSS];
\node (s32) [SusCirc=60];
\node (s33) [SusCirc=30];
    \node (ISS) [BigCirc,fit=(s31) (s33)];
%
\draw (SSS) -- (SSI) (SSS) -- (ISS); 
\end{tikzpicture}
\end{document}

为了使代码更简单、更紧凑，我使用了三个 tikz 库：（chain用于定位小圆圈）、fit（用于将大圆圈放在小圆圈周围，从而避免 tikz 图片嵌套）和positioning（用于定位圆圈组）。颜色强度选项的使用应该是自我描述的。

在此处输入图片描述

编辑：通过使用函数可以进一步简化我的代码default。上面的代码如下：

\documentclass[border=3mm,
               tikz]{standalone}
\usetikzlibrary{chains,fit,positioning}
    \definecolor{colorS}{RGB}{0,154,128}
    \definecolor{colorI}{RGB}{255,32,0}

\makeatletter
\tikzset{reset/.code={\def\tikz@after@path{}}}
\makeatother

\begin{document}
    \begin{tikzpicture}[
    node distance = 1mm,
      start chain = going right,
every node/.style = {draw=black!50, circle,
                     inner sep=0pt, minimum size=2mm,
                     node contents={}},
   SusCirc/.style = {fill=colorS!#1,% #1 determine color intensity 
                     join=by -, on chain},
SusCirc/.default = 90,
   InfCirc/.style = {fill=colorI!#1, join=by -, on chain},
InfCirc/.default = 90,
   BigCirc/.style = {very thick},
                        ]
\node (s11) [SusCirc];
\node (s12) [SusCirc];
\node (s13) [SusCirc];
    \node (SSS) [BigCirc,fit=(s11) (s13)];
%
\node (s21) [SusCirc,reset,
             below right=0mm and 55mm of SSS];
\node (s22) [SusCirc];
\node (s23) [InfCirc];
    \node (SSI) [BigCirc,fit=(s21) (s23)];
%
\node (s31) [InfCirc=50,reset,
             below right=21mm and 33mm of SSS];
\node (s32) [SusCirc=60];
\node (s33) [SusCirc=30];
    \node (ISS) [BigCirc,fit=(s31) (s33)];
%
\draw (SSS) -- (SSI) (SSS) -- (ISS); 
\end{tikzpicture}
\end{document}

好吧，这仍然不是您想要获得的，但是，请尝试以下步骤：

\begin{scope}[fill opacity=0.5% or whatever value you like to have
             ]
\node (s31) [InfCirc,reset,
             below right=21mm and 33mm of SSS];
\node (s32) [SusCirc];
\node (s33) [SusCirc];
\end{scope}

如果这令人满意，那么您可以省略 SusCirc 和 InCirc 的填充选项以及默认设置。
