| 摘要: |
| 时序数据在许多研究领域中都广泛存在.信息可视化是对时序数据进行分析的有力工具,然而已有的时序数据可视化技术无法较好地分析时间跨度长的时序数据.提出一种称为FisheyeLines的可视化技术,能够快速显示大数据集的整体视图,同时方便查看细节信息;能够清楚地表达复杂信息间的相互关系,同时可以显示对象的属性.基于FisheyeLines可视化技术,还给出了一种称为FisheyeLinesVis的可视化工具,可以方便地构造时序数据可视化应用.对以上技术和工具所构造的应用实例的分析与评估充分验证了该方法的有效性和易用性. |

| Abstract: |
| 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. |
