摘要

格在计算机科学和应用数学的许多领域起着重要的作用。在数据分析中从数据中提取或在智能系统中操作的信息通常由层次结构表示,其中关系由格描述。为了可视化信息,我们需要可视化格子。我们提到了现有的自动绘制网格的方法,重点介绍了Wille等人引入的几何方法。通过几何方法绘制的图表在满足通用约定和约束的同时,达到了良好的可读性和审美标准,即使对于较大的网格也是如此。我们讨论了有关该方法的几个问题,并展示了由捷克帕拉基大学计算机科学系开发的两个软件程序生成的图表。

Drawing lattices with a geometric heuristic
Lattices play an important role in many areas of computer science and applied mathematics. The information, extracted from data in data analysis or operated with in intelligent systems, is usually represented by hierarchical structures, where relationships are described by lattices. To visualize the information, one needs to visualize lattices. We mention the existing methods of automated drawing of lattices and focus on the geometric method introduced by Wille et al. Diagrams drawn by the geometric method achieve a good level of readability and aesthetic criteria while satisfying common conventions and constraints, even for larger lattices. We discuss several questions regarding the method and show the diagram drawings produced by two software programs developed at Dept. Computer Science, Palacky University, Czech Republic.
