mode. Chapters 4, 5, and 6 describe aspects that are unique
to parametric graphing, polar graphing, and sequence
graphing.
To define a graph in any graphing mode, follow these
steps. Some steps are not always necessary.
1. Press
z
and set the appropriate graph mode
(page 3

and enter, edit, or select one or more functions
in the

You can store the elements that define the current graph to
any of 10 graph database variables (
GDB1 through GDB9,
and
GDB0; Chapter 8). To recreate the current graph later,
simply recall the graph database to which you stored the
original graph.
These types of information are stored in a
GDB.

You can store a picture of the current graph display to any
of 10 graph picture variables (
Pic1 through Pic9, and Pic0;
Chapter 8). Then you can superimpose one or more stored
pictures onto the current graph.
