8) Scale relation guideline.
e) Problem: Users need to show different values of
attributes that can change through time.
f) Context of application: The user demands to visualize
time-oriented data, with phases and events related to a sample
in a temporary context. In this case, the user needs two separate
timelines to represent different facets of the phases or events
associated to the data.
g) Solution: Organize the information offering a
mechanism to relate two different timelines in the same
interface. This solution deals with Challenge 5.
h) Motivation: There is no solution to show data from
two timelines at the same timeline. Scale relation pattern
represents two separate timelines in the same interface showing
relations between them: overlapping between phases,
correspondence between events, etc.
All Guidelines are represented in Fig. 1 ordered by numbers
from 3.1 to 3.8, belonging to level 3.
