At the top of the Graph window (Figure 9.1) are several icons

icons act as expected allowing the user to quickly handle these func-

Selecting this icon places the current graph in an editing mode where
all of the various options and styles can be incorporated into the
graph. Such changes were made to the graph to produce the output
in Figure 9.2.
Figure 9.3 shows the Graph window after the Graph Editor icon
has been selected. In this mode, various elements of the graph can
