本文介绍了两种处理平行坐标的新技术。这两种技术本质上都是动态的，因为它们鼓励人们通过与数据集的交互来实验和发现新的信息。第一种技术，折线平均，使动态汇总一组折线成为可能，因此可以取代计算要求高得多的方法，如层次聚类。另一种新技术是交互地可视化折线子集之间的相关系数，帮助用户在数据集中发现新的信息。这两种技术都是在基于Java的并行坐标浏览器中实现的。最后，本文还探讨了这些技术在可视化数据挖掘中的应用实例。
This paper introduces two novel techniques to manipulate parallel coordinates. Both techniques are dynamic in nature as they encourage one to experiment and discover new information through interacting with a data set. The first technique, polyline averaging, makes it possible to dynamically summarise a set of polylines and can hence replace computationally much more demanding methods, such as hierarchical clustering. The other new technique interactively visualises correlation coefficients between polyline subsets, helping the user to discover new information in the data set. Both techniques are implemented in a Java-based parallel coordinate browser. In conclusion, examples of the use of these techniques in visual data mining are also explored.
