我怎样才能像上面那样在节点上方/下方创建两个小框?我已经写了一个标签,但它不起作用。

答案1
你不能[<options>]
在任何地方添加。在你的代码中你有
\node at (x,y) [<some style options>] {<node text>} [<label>];
但是在 之后不能有选项{<node text>}
,label
应该与您之前添加到节点的其他选项一起使用。
\node at (x,y) [<some style options>, <label>] {<node text>};
附注:记录的顺序是
\node [<options>] at (<coordinate>) {<node text>};
尽管它确实可以工作,正如您所写的一样。
对于您问题中的具体代码:
\node at ( 3,0)[roundnode, label={[draw,rectangle split,%<-selects shape
rectangle split parts=2,%<- 2 node parts
rectangle split horizontal,%<- horizontal split
yshift=-1ex]below:{10\nodepart{two}10}}] (node1) {1};
您还需要将\usetikzlibrary{shapes.multipart}
库添加到序言中才能使用rectangle split
。
