[. . . ] Recall a saved graph database. Storing a Graph Picture A picture includes drawn elements, plotted functions, axes, and tick marks. The picture does not include axis labels, lower and upper bound indicators, prompts, or cursor coordinates. Any parts of the display "hidden" by these are stored with the picture. The current graph is displayed and the picture is stored. Recalling a Graph Picture 1. Press y DRAW | (to display the DRAW STO menu) 2 (to select RecallPic). The current graph is displayed if necessary, and the picture is superimposed. You cannot TRACE any curve on a picture. Deleting a Graph Picture Graph pictures are deleted from memory through the MEM menu (Chapter 15. ) 8-14 DRAW Operations Storing and Recalling Graph Databases A graph database is the set of elements that define a particular graph. 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. 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. Press y DRAW | (to display the DRAW STO menu) 4 (to select RecallGDB). (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 Clearing a Drawing All points, lines, and shading drawn on a graph with DRAW operations are temporary. They remain only until you execute a ClrDraw (clear drawing) instruction or a change prompts Smart Graph to replot the graph, at which time all drawn elements are erased. When a Graph is Displayed To clear drawings from the currently displayed graph, select ClrDraw from the DRAW DRAW menu (item 1). The current graph is plotted and displayed immediately with no drawn elements. From the Home Screen or a Program Begin on a blank line on the Home screen or in the program editor. When the instruction is executed, it clears all drawings from the current graph and displays the message Done. The next time you display the graph, all drawn points, lines, circles, and shaded areas will be gone. Note: Before you clear drawings, you can store them with StorePic (page 8. 14). 8-16 DRAW Operations Chapter 9: Split Screen On the TI. 82, you can simultaneously display a graph (including a stat plot) and an editor such as the Home screen, Y= editor, list editor, or table editor.

The current graph is plotted in the standard viewing WINDOW (just compressed) and displayed on the top half of the display. The Y= editor displays on the bottom half of the display and the cursor moves to the Y= editor. 6. [. . . ] The software and any documentation supplied with this product are protected by copyright.
