| Abstract: | 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. |
