我想用 tikz 或不使用 tikz 绘制图表（下面给出了图表的图像）。我能够在一定程度上使用 texstack exchange 以前的问题，但无法对其进行修改以使其适合我。
参见代码和图片：
\documentclass{article}
\usepackage{tikz}
\begin{document}
\thispagestyle{empty}
\usetikzlibrary{positioning}
\tikzset{
node of list/.style = {
draw,
fill=orange!20,
minimum height=6mm,
minimum width=6mm,
node distance=6mm
},
link/.style = {
-stealth,
shorten >=1pt
},
array element/.style = {
draw, fill=white,
minimum width = 6mm,
minimum height = 10mm
}
}
\def\LinkedList#1{%
\foreach \element in \list {
\node[node of list, right = of aux, name=ele] {\element};
\draw[link] (aux) -- (ele);
\coordinate (aux) at (ele.east);
}
}
\begin{tikzpicture}
\foreach \index/\list in {1/{a,b,null}, 2/{c,null}, 3/{d,null}} {
\node[array element] (aux) at (0,-\index) {\index};
\LinkedList{\list}
}
\end{tikzpicture}
\end{document}
问题：我添加了以下几件事，第一件事是增加数组大小，第二件事是使链接列表具有 3 个单元格大小的节点，最后一件事是在一个链接列表上用一些文本画一个圆圈
答案1
如上所述，使用库的可选实现matrix，它具有用于矩阵中每个节点的样式和坐标的许多控制命令；此外positioning，，fit库arrows.meta允许稍微夸张的实现......
结果：

答案2
我会以稍微不同的方式编写宏。您的圆可以绘制为椭圆形。请注意，还有更多可能性。
- 您可以将其
shapes.multiparts用于画面。 - 您可以使用
chains 作为画面。 - 您可以使用
matrix来放置画面。如果画面宽度不同，这尤其有意义。
然而，这个答案的目的只是稍微修改您已有的内容。
