回答这个问题后问题，现在我的箭头看起来非常不令人满意。
如果我使用命令double中的选项，\draw间距会太小，而当我增加间距时，箭头看起来很糟糕。目前，箭头看起来很小，而且位置不对；我想要宽箭头（双箭头），箭头细。
我如何修改箭头（最好以全局方式）以使它们与绘图保持一致？
和，如何修改箭头使它们垂直于其指向的表面？

答案1
对于垂直箭头，我知道的唯一方法是保存正确的（x，y）坐标，并将箭头连接到这些坐标。
声明一些新的维度来保存坐标。
\newdimen{\myxdimone}
\newdimen{\myydimone}
\newdimen{\myxdimtwo}
\newdimen{\myydimtwo}
创建所需的路径，并使用 获取它们的 x,y 坐标\pgfgetlastxy{x}{y}，例如
\path (thrman.west);
\pgfgetlastxy{\myxdimone}{\myydimone};
\path (lib.east);
\pgfgetlastxy{\myxdimtwo}{\myydimtwo};
现在根据保存的尺寸创建一个坐标并绘制箭头。
\coordinate (dummy1) at (\myxdimtwo, \myydimone);
\draw[<->] (thrman.west) -- (dummy1);
可能有更简单的解决方案，但这是我在类似情况下使用的方法。请参阅下面的完整代码。

答案2
当你说
\draw[<->] (imgan.east)--(scrpts);
coordinate imgan.east您正在绘制一个从到 的箭头coordinate scrpts.center，但箭头将停止在scrpts边界处。
如果要从imgan.east一条水平线imgan.east和一条垂直线的交点处画一条箭头，scrpts.west可以使用特殊语法
\draw[<->] (imgan.east) -- (imgan.east-|scrpts.west);
由于scrpts.west和scrpts.center位于同一水平线上，因此您可以避免使用 进行一些输入(imgan.east-|scrpts)。
改变
\draw[<->] (imgan.east) -- (scrpts);
\draw[<->] (thrman.east) -- (scrpts);
\draw[<->] (thrman.west) -- (lib);
\draw[<->] (imgan.west) -- (lib);
\draw[<->] (dio.west) -- (lib);
\draw[<->] (daemon.west) -- (lib);
到
\draw[<->] (thrman.east) -- (thrman.east-|scrpts.west);
\draw[<->] (thrman.west) -- (lib.east|-thrman);
\draw[<->] (imgan.west) -- (lib.east|-imgan);
\draw[<->] (dio.west) -- (lib.east|-dio);
\draw[<->] (daemon.west) -- (lib.east|-daemon);
您将获得期望的结果。
