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. Note that CLRDRAW gives you a quick way to replot the current graph, in addition to clearing the current drawings. From the Home Screen or a Program Begin on a blank line on the Home screen or in the program editor. Select CLRDRAW from the DRAW DRAW menu (item 1). The instruction is copied to the cursor location. 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, and shaded areas will be gone. 7-12 Draw Operations
