Split Screen (only if you are using the two-graph mode).
¦ All functions in the Y= Editor ( ¥ # ), including display styles and
which functions are selected.
¦ Table parameters ( ¥ & ), Window variables ( ¥ $ ), and
graph formats ( ƒ 9 — or — TI - 89 : ¥ Í TI - 92 Plus : ¥ F .)

A graph database is the set of all elements that define a
particular graph. By saving a graph database as a GDB
variable, you can recreate that graph at a later time by opening
its stored database variable.
