Time-Pie visualization: Providing Contextual Information for Energy Consumption Data

Abstract

In recent years a growing number of information visualization systems have been developed to assist users with monitoring their energy consumption, with the hope of reducing energy use through more effective user-awareness. Most of these visualizations can be categorized into either some form of a time-series or pie chart, each with their own limitations. These visualization systems also often ignore incorporating contextual (e.g. weather, environmental) information which could assist users with better interpretation of their energy use information. In this paper we introduce the time-pie visualization technique, which combines the concepts of timeseries and pie charts, and allows the addition of contextual information to energy consumption data.
