摘要:: 传统多维数据可视化技术比如平行坐标法等在表达多维数据时,对各个不同数据维之间的数据表达式会产生一定的混乱,同时对各维的相关性与交互表达比较困难。研究并设计了基于VaR技术的多维数据交互可视化小工具,其充分利用VaR技术所实现的丰富导航与选择、突出等工具来形象突出显示与表达多维数据中某一特定维的数据,同时应用MDS算法,在二维屏幕上各点的相对位置关系来表示多维数据中各维的相关性

Abstract:: The traditional multi- dimensional data visualization technologies such as parallel coordihates in the expression of multidimensional data, the data among the various data - dimensional expression would produce a certain confusion and the relevance of the peacekeeping expressed difficulty with the rest of the world. In this paper, design a VaR technology multidimensional data world visualization tool,make full use of VaR technology to achieve the rich navigation and selection, highlighting the tools to image highlights and expression of multi- dimensional data of a particular dimension of data and apply multi - dimensional scaling algorithm in two- dimensional screen at various points in the relative position to show multidimensional data peacekeeping relevance
