我该如何纠正箭头的对齐？
答案1
正如我在评论中提到的那样，您的图像应该是什么样的并不完全清楚：
- 除了输入错误
southwest->south west - 您的图形太宽了，无法放入文本块中！它突出了页面边框（请参见代码图片，我只补充一点，
showframe您可以看到页面布局）
（红线表示您的文档页面布局）
- 您设想如何将其放在页面上？旋转图形是可接受的解决方案吗？
上图的 MWE 为：

%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}

更正southwest为south west：
我的问题是正确的对齐方式是什么？你想要怎样的对齐方式？
通过将每个替换south west为east，我得到：
