Tikz 比例键无法正确缩放坐标

Tikz 比例键无法正确缩放坐标

我使用 tikz 创建了一个图像，但缩放时它无法正确转换坐标，如下图所示。我认为这是因为使用了很多节点来绘制图像，特别是橙色和青色线条，这也是两条未缩放的线条。

Tikz 中的缩放比例

我现在很困惑，因为我创建的其他非常相似的图像确实可以正确缩放。我知道我可以使用诸如 之类的东西resizebox，但我不希望文本缩放。我真的很感激任何帮助 :)

MWE 如下：

好吧，我找到了方法。正如 J Leon V 所说，除非transform shape使用键，否则不会重新缩放节点，但这也会重新缩放文本。然而，这仅有的影响用声明的节点\node，但不是在路径/线的中间声明的节点。因此，我修改了代码，以便在创建图像上的线的同时声明我需要的节点。

现在它正常工作了。一切都缩放了，但文本仍然在它应该在的位置，并且保持它应该的大小。我在下面发布了修改，因此它可能可以为其他人提供参考 :)
