This paper proposes a new data analysis tool called Time-tunnel. Time-tunnel visualizes any numbers of time-series numerical data as individual charts in a 3D virtual space. Through direct manipulations on a computer screen, the user easily puts more than two different charts overlapped together to compare them in order to recognize the similarity or the difference among those data. Simultaneously a radar chart among those data at any time point is displayed to recognize the similarity and the correlation among them. In this way, using Time-tunnel, the user can visually analyse multiple time-series numerical data through interactive manipulations on a computer screen. Time-tunnel has not only aspects as a data analysis tool but also aspects as a chart-based multimedia presentation tool because Time-tunnel also treats multimedia data, i.e., texts, images, sounds and movies, as additional information represented by tags located at any point of charts. In this paper, the authors also describe the usefulness of Time-tunnel as a multimedia presentation tool.
