5.Drawing Two Graphs on the Same Screen

ICopying the Graph to the Sub-screen

Dual Graph lets you split the screen into two parts. Then you can graph two different functions in each for comparison, or draw a normal size graph on one side and its enlarged version on the other side. This makes Dual Graph a powerful graph analysis tool.

With Dual Graph, the left side of the screen is called the “main screen”, while the right side is called the “sub-screen”.

SMain Screen

The graph in the main screen is actually drawn from a function.

SSub-screen

The graph on the sub-screen is produced by copying or zooming the main screen graph. You can even make different V-Window settings for the sub-screen and main screen.

STo copy the graph to the sub-screen

1.From the Main Menu, enter the GRAPH mode.

2.On the Setup screen, select “G + G” for Dual Screen.

3.Make V-Window settings for the main screen.

Press (RIGHT) to display the sub-graph settings screen. Pressing (LEFT) returns to the main screen setting screen.

4.Store the function, and draw the graph in the main screen.

5.Perform the Dual Graph operation you want.

*(COPY) ... Duplicates the main screen graph in the sub-screen

*(SWAP) ... Swaps the main screen contents and sub-screen contents

•Indicators appear to the right of the formulas in the Graph relation list to tell where graphs are drawn with Dual Graph.

Indicates sub-screen graph (on right side of display)

Indicates graph drawn on both sides of display

Performing a draw operation with the function marked “ R ” in the above example screen causes the graph to be drawn on the right side on the display. The function marked “ B ” is drawn on both sides of the graph.
