1) Rows aggregation guideline.
a) Problem: Users need a general view of information
managed on interfaces with landscape orientation. In addition,
there is a need of consistency amongst other visualization
elements of the screen.
b) Context of application: The user demands to visualize
information in function of: a characteristic in a landscape
interface –avoiding scroll behaviors-, a characteristic based on
categories or based on intervals of values.
c) Solution: Organize the information in rows, creating
divisions per row in the interface. This allows an analysis from
left to right with a good distinction between the categories or
intervals of values. This solution deals with Challenge 1.
d) Motivation: The analysis based on categories or
intervals of values is a common practice in data-analysis
applications. Rows aggregation can help distribute analysis
results in landscape orientation intuitively.
