如何用间谍仅在放大的区域中书写

如何用间谍仅在放大的区域中书写

我想在放大区域添加大量评论,但我不知道该怎么做。你能帮帮我吗?

谢谢

在此处输入图片描述

答案1

\spy命令被推迟到当前范围的结束(tikzpicture在您的情况下),因为它需要了解整个情况。

将图片放在一个scope环境中,并在其后添加写入放大部分的命令,使后者可见。

代替

\begin{tikzpicture}[x=3cm, y=3cm,spy using overlaysshadow={magnification=2,connect spies}]

\begin{tikzpicture}[x=3cm, y=3cm]
\begin{scope}[spy using overlaysshadow={magnification=2,connect spies}]

最后替换

\spy[size=10cm] on (0.25,0.25) in node at (3.33,-1.66);

\node[below,ultra thick] at (3.33,-1.66) {$T_A$};
\end{tikzpicture}

\spy[size=10cm] on (0.25,0.25) in node at (3.33,-1.66);
\end{scope}    
\node[below,ultra thick] at (3.33,-1.66) {$T_A$};
\end{tikzpicture}
