Few tools exist for data exploration and pattern identification in time series data sets. Timeboxes are rectangular, direct-manipulation queries for studying time-series datasets. Timeboxes are the primary query tool in our TimeSearcher application, which supports interactive exploration via dynamic queries, along with overviews of query results and drag-and-drop support for query-by-example. This paper describes the TimeSearcher application and possible extensions to the timebox query model, along with a discussion of the use of TimeSearcher for exploring a time series data set involving gene expression profiles.
