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. Storing a Graph Database 1. Press y ãDRAWä | (to display the DRAW STO menu) 3 (to select StoreGDB). StoreGDB is copied to the Home screen or program editor. 2. Press 3 (to display the VARS GDB menu). Select GDB1, GDB2, GDB3, GDB4, GDB5, or GDB6. 3. Press Í. The current database is stored. StoreGDB GDBn Recalling a Graph Database Caution: When you recall a graph database, all existing Y= functions are replaced. You may want to store the current Y= functions to another database before recalling a stored database. 1. Press y ãDRAWä | (to display the DRAW STO menu) 4 (to select RecallGDB). RecallGDB is copied to the Home screen or program editor. 2. Press 3 (to display the VARS GDB menu). Select GDB1, GDB2, GDB3, GDB4, GDB5, or GDB6. RecallGDB GDBn 3. Press Í. The new graph database replaces the current one. The new graph is not plotted. (The TI.82 changes graphing MODE automatically, if necessary.) Deleting a Graph Database Graph databases are deleted from memory through the MEM menu (Chapter 15.) DRAW Operations 8-15
