These maps are created by ViSta as the data analysis session progresses. They aid novice and competent analysts in remembering their analysis session, and permit the analyst to return to earlier steps of the analysis. These maps are created by experts using ViSta's Authoring tools. ViDAL is an extension of the underlying Lisp-Stat language that can be used by sophisticated data analysts for data analysis and by programmers to enhance ViSta's capabilities. A graphical datasheet for displaying and editing data.
Plots support brushing and labeling, and are dynamically linked.
