如何在 tikz 的矩形块中使用项目符号和新行？以及如何从矩形分割节点的特定位置绘制箭头？

Question

我想要画这样的东西：

这就是我得到的：

我面临三个困难：

1. 如何在块内添加项目符号？以及如何对同一块使用不同的字体？
2. 如何绘制其余的箭头。
3. 如何得到图中arr2下方的三个圆圈？

这是我的 tikz 代码：

Answer 1

项目符号

要放置项目符号，我只需\draw在适当的点处画一个圆圈即可。对于多部分，split rectangle您可以访问第二部分，例如，如a5.two。我们希望在第二部分的南面下方，因此您可以使用：

\draw [blue]  ($(a5.two south)+(0,-0.5cm)$)   circle (4pt);

这里我使用了 tikz 的calc库来将位置(0,-0.5cm)从移开a5.two south。棕色节点使用 以类似的方式放置。要放置红色节点，我使用计算和(a5.three south)之间的中点，然后也将其垂直移动。因此，“项目符号”的完整代码是：(a5.two south)(a5.three south)(a5.two south)!0.5!(a5.three south)

\coordinate (midway) at ($(a5.two south)!0.5!(a5.three south)+(0,-0.5cm)$);
\draw [blue]  ($(a5.two south)+(0,-0.5cm)$)   circle (4pt);
\draw [red]   (midway)                        circle (4pt);
\draw [brown] ($(a5.three south)+(0,-0.5cm)$) circle (4pt);

字体更改：

更改字体的一种方法是使用

 font=\Large\bfseries

我还添加了使文本居中并使用\\您可以添加的align=center。

项目符号节点内容

由于您想要list在中使用类似的环境，node您可以将节点内容放在里面\parbox，然后使用该itemize环境并应用任何字体更改，就像在外面一样tikzpicture：

\parbox{6.5cm}{\color{blue}%
\begin{itemize}
    \item dimension
    \item bounds in each dim 
\end{itemize}%
}

箭：

我用了

\draw [ultra thick, blue, ->] 
    (a1.east) -- 
    ($(a1.east)+(0.5cm,0)$) |- (b7.west);

绘制其中一个箭头。
