(按建议编辑)
我有以下涉及连接节点的代码:
\documentclass{article}
\usepackage{tikz}
\tikzstyle{every picture}+=[remember picture]
\begin{document}
\begin{equation}
P(t) =
\tikz[baseline]{\node[fill=blue!50, anchor=base] (t1) {$
\epsilon_{0}\chi^{(1)}E(t)
$};}
+
\tikz[baseline]{\node[fill=red!50, anchor=base] (t2) {$
\tikz[baseline]{\node[fill=green!25, anchor=base] (t21) {$
\epsilon_{0}\chi^{(2)}E^{2}(t)
$};}
+
\tikz[baseline]{\node[fill=yellow!25, anchor=base] (t22) {$
\epsilon_{0}\chi^{(3)}E^{3}(t)
$};}
+ \cdots
$};}
\end{equation}
\begin{itemize}
\item \tikz[baseline]{\node[anchor=base] (n1) {Linear};}
\item \tikz[baseline]{\node[anchor=base] (n2) {Nonlinear};}
\begin{itemize}
\item \tikz[baseline]{\node[anchor=base] (n21) {2. order};}
\item \tikz[baseline]{\node[anchor=base] (n22) {3. order};}
\end{itemize}
\end{itemize}
\begin{tikzpicture}[overlay]
\path[blue, ->, line width=1pt] (n1.north east) edge[out=45, in=-90] (t1.south);
\path[red, ->, line width=1pt] (n2.north east) edge[out=45, in=-90] (t2.south);
\path[red, ->, dashed, line width=0.75pt] (n21.east) edge[out=0, in=-90] (t21.south);
\path[red, ->, dashed, line width=0.75pt] (n22.east) edge[out=0, in=-90] (t22.south);
\end{tikzpicture}
\end{document}
此代码给出以下输出,其中是节点 t2 内部 x 坐标的偏移量:
如果我注释掉此节点(t2)的创建,则虚线箭头现在指向正确的位置:
我想要的是第一个图(红色实线和红色填充),其中虚线箭头指向第二个图所示的位置。有办法吗?
非常感谢你的建议
