Week 7-9

Issue

• KDE Method: little insight

• Global measure on the brushed period takes time to compute

To Do

• Interaction

  • timeline with nearest value —— how?

  • a vertical line and tooltip √

  • do more with the degree distribution √

  • click and change time slider √

  • zoom effect for all timelines √

  • group selection and highlight

• Layout

  • a compact timeline view √

  • title alignment √

  • padding in the bars √

  • use brightness to encode different layers √

• Data Processing

  • separate time intervals according to natural division √

    • a more natural way other than fixed interval

  • global measure on the brushed period (toggle on) √

  • bandwidth slider with a clearer indication √

• Bugs and Small Issue

  • tick marks √

  • "connected nodes" √

• Other Views

  • reorder-able parallel coordinate √

• Data

  • try more new data and write a summary

To Think

• interpretation on the multi-layer timeline view

KDE

Challenge: convert the quantity distribution to date distribution

Strategy: linear transformation from timestamps to values
