Storing and Recalling Graph Databases
A graph database is the set of elements that define a particular graph. The graph
can be recreated from these elements. You can store up to six graph databases
and recall any of them to recreate a graph at a later time.
Graph Databases
The elements of a graph database are:
¦
Graphing
MODE
.
¦
WINDOW
variables and
WINDOW FORMAT.
¦
All functions in the
Y=
list, and whether they are selected.
Graph databases do not include any drawn items or any
Stat Plot
definitions.
