INTERACTIVE DATA VISUALIZATION FOR TREND ANALYSIS

摘要

A method and system for identifying a trend in data of heat maps. An initial set of comparison heat maps included in the repository is determined and displayed based on how closely initial comparison area(s) of each comparison heat map match initial target area(s) of a first heat map. A review of the initial set of comparison heat maps determines additional comparison area(s) corresponding to additional target area(s) of the first heat map. In an iterative process, an additional set of comparison heat maps is determined and displayed based on how closely initial and additional comparison areas match respective initial and additional target areas of the first heat map. A trend relating initial and additional target areas is identified based on the displayed additional set of comparison heat maps and based on how closely comparison areas match their respective target areas.
