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 stored GDB.
To recall a graph database, follow these steps.
1. Select 4:RecallGDB from the DRAW STO menu. RecallGDB is pasted to the current cursor location.
2. Enter the number (from 1 to 9, or 0) of the
GDB variable from which you want to recall a GDB. For
example, if you enter 7, the TI-84 Plus C will recall the
GDB stored to GDB7.
Note: You also can select a variable from the GDB secondary menu ( 3). The variable is pasted
next to RecallGDB.
3. Press Í to replace the current GDB with the recalled GDB. The new graph is not plotted. The
TI-84 Plus C changes the graphing mode automatically, if necessary.

To delete a GDB from memory, use the MEMORY MANAGEMENT/DELETE secondary menu (Chapter 18).
