In Proceedings of the 12th Annual Conference of the New Zealand Chapter of the ACM Special Interest Group on Computer-Human Interaction, 4-5 July 2011, Hamilton, New Zealand.https://hdl.handle.net/10289/5753Meters and gauges based on analogue pointers provide a convenient way to visualise single dimensional data streams, such as speed, voltage, altitude, or fuel level. However, often a small amount of historical information helps to understand the data at a glance, and reduces the need for constant vigilance; is the parameter relatively stable; is it increasing or decreasing? Have there been any transients in the past minute? What trends are present? This paper describes a virtual analogue meter with a flexible pointer that shows both the instantaneous value at the tip and bends to a brief interval of history along its length. The meter has been developed in the context of monitoring the electricity grid, but has many other potential applications.application/pdfenThis is the author’s accepted version of an article published in Proceedings of the 12th Annual Conference of the New Zealand Chapter of the ACM Special Interest Group on Computer-Human Interaction, 4-5 July 2011. © 2011 ACM.computer sciencemeter displaydashboardenergy monitoringhistory visualisationConference Contribution10.1145/2000756.2000769
