Abstract: The areas of social science,environmental monitoring,financial and economic,health and geographic information have generated a large amount of time-varying multivariate data.With a depth analysis of the time-varying multivariate datasets,we proposed a layout algorithm for Radial Tree integrated metric properties called LAMPRT to demonstrate metric properties.And then,we proposed another layout algorithm called LOVEBRT to exhibit the time-varying feature.These two algorithms and some human-computer interaction techniques both form the visualization method TVBRT.Case studies demonstrate the effectiveness of this method,showing that the method is more effective in exhibiting more details of the datasets.TVBRT outperforms over other methods in exhibiting data in a hierarchical and more accurate way.
