摘要
在图的最优可视化过程中,当图的边和节点都包含文字或图形标签时,显示这些标签必须保证它们互相不重叠.这项工作可以融入初始布局的一部分,或作为后处理步骤.去除重叠的核心问题在于保持布局中固有的结构信息,最大限度地减少所需的额外面积,并保持边尽可能地直.提出了一种同时去除节点和边的标签重叠的计算方法.该算法基于最小化一个目标函数,使得图的布局尽少改变,并保持边的平直.
When drawing graphs whose edges and nodes both contain text or graphics, such information needs to be displayed without overlaps, either as part of the initial layout or as a post processing step. The core problem in removing overlaps lies in retaining the structural information inherent in a layout, minimizing the additional area required, and keeping edges as straight as possible. This paper presents a combined node and edge overlap removal algorithm that aims at offering one solution to this problem, based on minimizing a cost function that both reduces topological changes to the original drawing, and keeps edges straight.
