基于雷达图的多维数据可视化表示及特征分析

Visualization Representation and Feature Analysis of Radar-map-based Multi-dimensional Data

针对雷达图分析方法中存在的问题,讨论了用雷达图表示多维数据的数学模型,综合分析了可视化图形几何特征及其应用方法,建立了基于可视化图形分类的准确度的估算方法和按权重大小定义多维数据顺序的方法,有效地解决了传统雷达图分析方法中存在的面积不惟一等问题。

The mathematical model of the multi-dimensional data represented by radar map is discussed to solve the problems existing in the radar-map analysis. The geometric features of the visual graphic and its applications are analyzed comprehensively. The methods to estimate the accuracy of the presentation based on the visual graphic classifications and define the multi-dimensional data sequence in accordance with weighting based on the related criteria are established, which effectively solve the problems （such as the area that is not unique） existing in the traditional radar map analysis.
