There are many very good power quality data analysis tools, but they are often vendor specific, and designed as an engineering desktop tool. This presentation is an introduction to a 'fleet view' dashboard built in the open source software (OSS) space. It is web based, built on an open source data layer that provides automated analytics, and can accept data from any standard COMTRADE or PQDIF formatted event file.

Dashboard vs Analytic Software
http://www.exceldashboardwidgets.com/
Analytics is the discovery and communication of meaningful patterns in
data. Especially valuable in areas rich with recorded information,
analytics relies on the simultaneous application of statistics, computer
programming and operations research to quantify performance. Analytics
often favors data visualization to communicate insight. (wikipedia)
