This section describes how to enlarge and reduce the size of a graph, how to change the eye 
position to view the graph along a particular axis, and how to perform other operations like 
automatic rotation. 

• All of the operations described in this section can be performed only while the 3D Graph 

window is active. 

A displayed 3D graph can be zoomed so it is enlarged or reduced. The zoom operation is 
always performed based on the center of the Graph window. You cannot select the area to 
be zoomed.
