  1. BinX Dynamic binning for time series Project update Information Visualization - CS533c Lior Berry March 15th 2004

  2. Motivation • Time series are ubiquitous and important • Lots of information = long series • Understanding a long time series is hard ! • Comparing two time series is even harder !!

  3. The Data & tasks • Daily currency exchange rates over several years • Comparing different time periods • Comparing two currencies

  4. Proposed approach • Binning over time intervals simplifies exploration and comparison • Dynamic binning (continuous) • Mitigating information loss in bins (visual encoding, “glyphs”)

  5. Visualization approach • Clear spatial cues • Mix and match • Context maintenance Trapezoidal Spiral / Circular

  6. Related work Dynamic Aggregation with Circular Visual Designs, Mei C. Chuah

  7. Related work • Cluster and Calendar based Visualization of Time Series Data, Wijk, Selow • Interactive Visualization of Serial Periodic Data, Carlis, Konstan

  8. Project state • Currency data assembled (fxhistory *) • Application framework using Java2D • Data parsed and processed • Focus on spiral display • Basic Interaction (keyboard based) * http://www.oanda.com/convert/fxhistory

  9. “Demo”

  10. “Demo” continued

  11. “Demo” continued

  12. “Demo” continued

  13. “Demo” continued

  14. “Demo” continued

  15. Milestone check • Preparation of test data • Prototype of visualizations and basic interactions (dynamic change of bin size) • Finalizing the visualization paradigm • GUI + Linked navigation implementation • Implementing bin similarity display, based on clustering (+ consideration of displaying other indicators)

  16. Summary • Dynamic binning can be a powerful aid • Visual cues to assist the user • Questions ?
