摘　　要：阐述了统计数据的时空特性,扩展了动态空间可视化的动态视觉参量,设计了3种用于多时相统计信息动态空间可视化的"动态统计图表"。采用时间地图动画技术及关键帧插值动画技术来设计与构建动态统计图表,并将此方法应用于相应系统,实现了统计数据随时间变化动态特性的可视化表达。By describing the spatial-temporal characteristics of statistical data and extending the dynamic visual parameters of dynamic spatial visualization,three types of dynamic statistical charts are designed.Those charts are based on dynamic spatial visualization of electronic map and are used in representing the multi-temporal statistical information.According to time factor technology using in map animation and the interpolation technology using in the key-frame,the idea and the flow of dynamic statistical charts are designed and built.Meanwhile,the research results was adopted in a program,which realized the visualization expression of the statistical data which is changing as time.Finally,we achieved the expected effect of dynamic spatial visualization expression of statistical data,which indicating that the research has certain promotion value.
