11-4 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.

Active (Left) Screen Inactive (Right) Screen
View Window parameters View Window parameters
Xmin = –2 Ymin = –2 Xmin = –4 Ymin = –3
Xmax = 2 Ymax = 2 Xmax = 4 Ymax = 3
Xscale = 0.5 Yscale = 1 Xscale = 1 Yscale = 1
Assume that the function being graphed is stored in memory area Y1.
