一种面向层次和时序结构的多维可视化技术

A Visualization Technique for Multidimensional Data with Hierarchical and Temporal Structure

多维数据、层次数据和时序数据在许多领域中都广泛存在。实际中的数据常常同时具有这三种数据类型的结构特征。信息可视化是对数据进行分析的有力工具，然而已有的可视化技术无法较好地分析具有复合结构特征的数据。针对这种问题，本文提出一种新型的可视化技术，该技术能够快速显示复合结构数据集的整体视图，同时还能很方便地查看细节信息，并提供各种交互手段进行可视化分析。基于这种技术开发的WHU—HTMVIS软件能够快速构造层次时序多维数据可视化应用。实例分析验证了该技术和软件的有效性和易用性。

Multidimensional data, hierarchical data and temporal data are widely used in many fields, and the actual data often simultaneously possesses structural properties of these three types of data. One of the prominent data analysis techniques is information visualization, but users tend to fail to analyze compound structure data with existing approaches. This paper presents a new visualization technique , trying to resolve the problems. This visualization technique provides good overviews for large-scale information and details for these focus objects. Meanwhile, it provides various ways of human-computer interaction to process visual analytics. It also presents a tool named WHU-HTMVIS for developing multidimensional data with hierarchical and temporal structure visualization application. A case study shows that the technique is efficient and easy to use.
