BinX Dynamic exploration of time series

This report presents the findings of a project focused on the dynamic exploration of time series data, specifically analyzing daily currency exchange rates over a 15-year period. The visualization principles employed include aggregating data over time intervals, enabling smooth navigation, maintaining context, and providing clear feedback. Key lessons learned highlight the importance of combining detail and overview, the benefits of animation in reducing cognitive load, and the flexibility offered by a mix-and-match approach to data exploration. Insights gained can benefit future visualizations and data analysis.

Presentation Transcript

  1. BinX Dynamic exploration of time series Final project report Information Visualization - CS533c Lior Berry April 20th 2004

  2. Motivation • More time dependent information is gathered • Long time series • Unsuitable for static visualization ScreenShot adapted from the TimeSearcher tool (UMD)

  3. The Data & tasks • Daily currency exchange rates over 15 years (5000 data points) • Comparing different time periods • Comparing two currencies

  4. Visualization principles • Aggregating over time intervals • Smooth navigation • Maintaining context + clear feedback • Multiple views (Linking)

  5. Visualization metaphor

  6. Demo

  7. Lessons learned • Detail + overview is invaluable • Animation reduces cognitive load • Mix and match allows flexible exploration • Extending the marking mechanism

  8. Thank you • Questions ?
