代码相同，但重新安装 MikTex 后生成不同的 pdf 文件

Question

的语法atan2在版本 3 中发生了变化，交换了参数的顺序。原因是，在此函数的所有实现中，是坐标在前，而在旧 PGF 版本 2 中，坐标必须按以下顺序给出坐标。

如果您想要一个可以使用 TikZ/PGF 版本（2 或 3）进行编译的文档，您可以定义自己的函数，根据版本号改变其行为。

在这里，我在序言中定义了一个Xatan2与版本 3 具有相同语法的函数atan2。当使用 TikZ/PGF 版本 2 编译文档时，该函数会调用atan2但交换参数；否则它只是调用atan2。

我已经相应地改变了你的宏定义，以便是-坐标优先。

我使用 TeX Live 2012（TikZ/PGF 版本 2.10）或 TeX Live 2013（TikZ/PGF 版本 3.0.0）进行编译得到的结果是相同的。
