5) Timeline IU.
a) Problem: Users need features related to time-oriented
analysis, especially in the analysis of time-oriented attributes –
attributes with different values through time-.
b) Context of application: The user demands to see
changes in values of attributes through time and to relate them
to other data.
c) Solution: Organize the information to select, display
and change time-oriented attributes in a time-oriented interface.
This solution deals with Challenge 5.
d) Motivation: The analysis based on time-oriented data
allows the user to reason out temporal dependencies among data. For instance, the user can see how the values of two
attributes change through time to analyze possible influences
between them.
