Temporal data are widely used in many fields. One of the prominent time series analysis techniques is visualization, which may improve users’ ability in information recognition and analysis. However, users tend to fail when analyzing a long time series with existing approaches. This paper presents an approach named FisheyeLines. This visualization technique provides good overviews for large-scale information and details for these focus objects. Meanwhile, the correlation between complex information and properties of objects are easily to be acquired. It also presents a tool named FisheyeLinesVis for developing temporal data visualization application. A user study shows that this approach is efficient and easy to use.
