PP: Composite visual mapping for time series visualization
However:
The conventional visual mapping maps each data attribute onto a single visual channel
Purpose:
investigate composite visual mapping综合可视映射: mapping single data attributes onto several visual channels.
a valuable tool for understanding those relationships and patterns and eventually for problem solving and decision making
Introduction:
Visual Problem: It's a challenge to view all data and information in a limited screen space.
Supplementary knowledge:
