Solution 18229: Storing and Recalling the Graph Elements on the TI-83 Family,TI-84 Plus Family, and TI-Nspire™ Handheld in TI-84 Plus Mode.

How can I store all the graphing elements on a TI-83 family, TI-84 Plus family, or TI-Nspire handheld in TI-84 Plus mode?

All of the elements that define a particular graph can be stored to a graph database (GDB) on the calculator, allowing  the user to recreate the graph at a later time. A GDB is different than a picture in that a GDB stores the elements that make up the resulting graph, instead of simply the output.

The following elements are contained in a GDB:

1) Graphing mode.
2) Window variables.
3) Format settings.
4) All functions in the Y= editor and the selection status of each.
5) Graph style for each Y= function.
6) You can have up to 10 GDB's stored in the calculator's memory at any given time.

Please Note: GDB's do not contain drawn items or stat plot definitions.

For more information on using pictures, please see the case entitled Opening Picture Files on a TI-83 Family, TI-84 Plus Family, or TI-Nspire Handheld in TI-84 Plus Mode.

Storing a graph database:

1) Press [2nd] [DRAW] then press the right arrow key twice to select the DRAW STO menu.
2) Press [3] to select 3:StoreGDB.
3) Input the number (0-9) of the GDB variable to which you want to store the graph database.
Please Note: You can also select a variable from the GDB secondary menu by pressing [VARS] [3].
4) Press [ENTER] to store the current database to the specified GDB variable.

Recalling a graph database:

CAUTION: When you recall a GDB, it replaces all existing Y= functions.  Consider storing the current Y= functions to another database before recalling a GDB.

1) Press [2nd] [DRAW] then press the right arrow key twice to select the DRAW STO menu.
2) Press [4] to select 4:RecallGDB.
3) Input the number (0-9) of the GDB variable from which you want to recall a graph database.
Please Note: You can also select a variable from the GDB secondary menu by pressing [VARS] [3].
4) Press [ENTER] to replace the current database with the recalled GDB.

For additional information on graph databases and other features, refer to the TI-83 family and TI-84 Plus family guidebooks.

Please Note: TI-Nspire users may refer to the TI-84 Plus family guidebook.
