Recalling Graph Pictures (Pic) Recalling a Graph Picture To recall a graph picture, follow these steps. 1. Select 2:RecallPic from the DRAW STO menu. RecallPic is pasted to the current cursor location. 2. Enter the number (from 1 to 9, or 0) of the picture variable from which you want to recall a picture. For example, if you enter 3, the TI-84 Plus will recall the picture stored to Pic3. Note: You also can select a variable from the PICTURE secondary menu ( 4). The variable is pasted next to RecallPic. 3. Press Í to display the current graph with the picture superimposed on it. Note: Pictures are drawings. You cannot trace a curve that is part of a picture. Deleting a Graph Picture To delete graph pictures from memory, use the MEMORY MANAGEMENT/DELETE secondary menu (Chapter 18). Storing Graph Databases (GDB) What Is a Graph Database? A graph database (GDB) contains the set of elements that defines a particular graph. You can recreate the graph from these elements. You can store up to 10 GDBs in variables GDB1 through GDB9, or GDB0 and recall them to recreate graphs. A GDB stores five elements of a graph. • Graphing mode • Window variables • Format settings • All functions in the Y= editor and the selection status of each • Graph style for each Y= function GDBs do not contain drawn items or stat plot definitions. Storing a Graph Database To store a graph database, follow these steps. Chapter 8: Draw Instructions 135
