我想要两个图（代数函数图）水平放置在节点内。我希望它们有符号，所以需要一些类似标题的东西（位于图下方）。
其中一个——“好的情况”——位于节点左侧，而“坏的情况”位于右侧。
下面是我的代码示例。它可以编译。取消注释后，它可以提供解决方案，但不幸的是，它不能。一目了然——只需编译，然后像我一样对输出不满意。

\begin{center}
\begin{tikzpicture}[remember picture]
\node[fill=white,rounded corners,text width=16cm,text=black,align=right]
(teacher1) {Some text goes here};
\node[fill=white,rounded corners,text width=16cm,text=black,align=left,below=of teacher1]
(teacher2) {And here goes the thought and its illustration by means of two plots:
\begin{tikzpicture}[remember picture]
\node (good) {
\begin{tikzpicture}
\node (origingreen) {};
\node[above=of origingreen] (topgreen) {};
\node[right=of origingreen] (rightgreen) {};
\draw [green, thick, samples=50,domain=0:5] plot (\x, {\x + sin(\x r)});
\draw [->] (origingreen) -- (rightgreen) node [right] {\text{t}};
\draw [->] (origingreen) -- (topgreen);
\end{tikzpicture}
%\caption{The good case; well, actually, this caption is really long in my paper}
};
\node[right=of good] (bad) {
\begin{tikzpicture}
\node (originred) {};
\node[above=of originred] (topred) {};
\node[right=of originred] (rightred) {};
%\draw [red, thick, samples=50,domain=0:5] plot (\x, {(\x*\x*\x)* exp(-\x)});
\draw [->] (originred) -- (rightred) node[right=1pt] {t};
\draw [->] (originred) -- (topred);
\end{tikzpicture}
%\caption{The bad case; well, actually, this caption is really long in my paper}

\end{tikzpicture}
};
\begin{scope}[on background layer]
\node [fill=cyan,fit=(teacher1) (teacher2)] {};

以下方法也不起作用（如果将图形粘贴到节点中，则图形不好）：

答案1
这是不使用嵌套的建议tikzpicture。为了定位图，我使用简单地origingreen相对于节点定位。轴线已经相对于原点绘制，因此剩下的就是移动图，您可以通过添加到宏的选项中来实现。teacher2\coordinate (origingreen) at ([yshift=-5cm,xshift=0.5cm]teacher2.south west);shift=(origingreen)\draw
由于标准文章中的文本块窄于 16 厘米，因此我还擅自将图表的宽度设为不超过\textwidth。
此处的标题只是作为节点添加的，文本位于原点下方。如果您需要实际编号的标题，请在节点文本中添加\usepackage{caption}，并使用\captionof{figure}{caption text}，而不仅仅是caption text。（请参阅下面的第二个示例。）
最后，使用该库在背景层上也绘制了绘图后面的白色背景fit。
