The contents of a Window can always be viewed as a table of values. You can view data in its numeric form by toggling the graph style using the toolbar button or by typing TABLE from the current Window, or by selecting Styles, Table, from the View pull-down menu.
For example, a line graph becomes a single column of numbers in table form while a more complicated image is displayed as a multi-column table. Refer to Chapter 6, "Special Topics in Data Display and Analysis" for a detailed discussion of table manipulation techniques.
