我已经用一条路径连接了两个节点：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\begin{document}
\tikzmarknode[inner sep=2pt,draw]{surname}{\mbox{Kennedy}} was killed in an assasin.
\vspace{5pt}
\begin{tikzpicture}[remember picture, overlay]
\draw[blue,thick,->](surname.south west) --++ (0,-1) node [below, draw]{\footnotesize b. May 29, 1917, d. November 22, 1963, often referred to by his initials JFK, 35th president of the USA from 1961 to 1963};
\end{tikzpicture}
\end{document}
由于路径默认连接到中心节点的上边缘，因此节点的左侧部分超出了页面。为了解决这个问题，我修改了node以下选项：
node [below right=-10pt, draw]
node [below, right=-10pt, draw]
node [below, center=-10pt, draw]
它们都没有帮助（我尝试了不同的选项大约一个小时）我在 TikZ 文档中搜索了该特定信息，但也没有任何帮助。
如何设置路径连接到节点的精确位置，以便节点位于屏幕截图中给出的所需位置？
答案1
您可以使用xshift来移动节点：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\begin{document}
\tikzmarknode[inner sep=2pt,draw]{surname}{\mbox{Kennedy}} was killed in an assasin.
\vspace{5pt}
\begin{tikzpicture}[remember picture, overlay]
\draw[blue,thick,->](surname.south west) --++ (0,-1) node [below, draw,anchor=north west,xshift=-3cm]{\footnotesize b. May 29, 1917, d. November 22, 1963, often referred to by his initials JFK, 35th president of the USA from 1961 to 1963};
\end{tikzpicture}
\end{document}
