Latex中画出函数文件的调用关系拓扑图

83 阅读 0 评论 55 点赞

我是靠谱客的博主细心战斗机，这篇文章主要介绍Latex中画出函数文件的调用关系拓扑图，现在分享给大家，希望可以做个参考。

流程图，思维导图，拓扑图通常能把我们遇到的一些复杂的关系结构用图形的方式展现出来。在Latex中要想画这样的拓扑图，有一个很好用的绘图工具包 pgf/tikz 。

1.pgf/tikz的安装：pgf/tikz 绘图工具用到的宏是 usepackage{tikz} 。如果你的Latex并不带有这个宏包，那就需要参考[1]中进行安装。也可以直接下载使用带有这个宏包的新版本 CTeX_2.9.2.164_Full。

2.pgf/tikz的使用：参考[2]pgf/tikz使用说明，这里详细介绍了pgf/tikz的各种用法。
