我想用shopping carttikzpicture 替换每个红色方形节点（购物车内不需要文字）：

\draw [line width=2pt] (-2.40,2.16)-- (0.84,2.16);
\draw [line width=2pt] (0.84,2.16)-- (0.59,2.67);

将购物车缩放到与方形红色节点类似的大小。
我怎样才能用手推车代替方形节点？（例如，c1、c2 和 c3 将是节点 1 右侧的三辆手推车）。
答案1
制作 Ti 有 2.5 种方法钾Z图片a节点：
- 使用
path picture。 - 用一个
\savebox。 - 使用
pics。严格来说，这不是一个节点，因此是“2.5”，而不是 3 种可能性。
让我们关注选项 2。您的购物车存储在 中\savebox。它可以是节点的内容，也可以使用 使其成为样式node contents。（在这种情况下，您需要对语法更加小心，\node (C1) [cart];有效但\node[cart] (C1);无效。）然后有几个题外话：
- 你加载了未使用的包和库。我已删除它们。
- 您正在加载
positioning但未使用它。请right of=A使用positioning语法right=of A或right=<distance> of A。这使得排列节点变得更加容易。 - 如果重复使用相同的样式，使用
scopes 会更方便。
所有这些在某种程度上都是在以下 MWE 中完成的（尽管并未完全优化）：
