If you see any pattern in a display window, Argos and Panmo allow you to retrieve the data generating the pattern immediately. Graphical query formulation wins big when there are patterns that are apparent on the screen but are tedious or difficult to describe in a textual query language. Being incremental, graphical query formulation avoids the error-prone process of specifying long text queries. By emphasizing the use of plots, it encourages users to browse and familiarize themselves with the patterns in their data, ultimately giving them a better understanding of it.
