Displaying a Graph in the Inactive Screen

There are two methods you can use to display a graph in the inactive screen. You

can copy a graph from the active screen to the inactive screen, or you can move

the graph from the active screen to the inactive screen. In both cases, you must

first draw the graph in the left-side active screen.
