以下代码中的 TikZ 图片无法正确缩放。它与文本重叠。如果我注释掉transform canvas={scale=0.5}它，它就可以正常工作（但我想缩放所有内容）。

答案1
transform canvas通常应该是最后手段：它使得 TikZ 失去对节点位置的跟踪，因此造成的危害大于好处。
就你的情况而言，scale=0.5如果你让节点也可扩展，那么一个简单的方法就可以了。默认情况下，TikZ 假定你不想缩放节点，因为这会改变文本大小。你可以tikzpicture通过添加来更改此行为every node/.append style={transform shape}：
或者，你可以使用\scalebox{0.5}{ \schema }：
