Split Screen Lets you split the screen into two parts. For example, you can display a graph and see the Y= Editor at the same time. 1:FULL 2:TOPBOTTOM 3:LEFT-RIGHT The screen is not split. The applications are shown in two screens that are above and below each other. The applications are shown in two screens that are to the left and right of each other. To determine what and how information is displayed on a split screen, use this mode in conjunction with other modes such as Split 1 App, Split 2 App, Number of Graphs, and Split Screen Ratio. (Split Screen Ratio is available on the Voyage™ 200 only.) Split 1 App and Split 2 App Specifies which application is displayed on the screen. • For a full screen, only Split 1 App is active. • For a split screen, Split 1 App is the top or left part of the screen and Split 2 App is the bottom or right part. The available application choices are those listed when you press B from the Page 2 mode screen or when you press O. You must have different applications in each screen unless you are in 2-graph mode. Number of Graphs Specifies whether both parts of a split screen can display graphs at the same time. 1 Only one part can display graphs. 2 Both parts can display an independent graph screen (Graph or Graph 2 setting) with independent settings. Graph 2 Specifies the type of graphs that you can plot for the second graph on a two-graph split screen. This is active only when Number of Graphs = 2. In this two-graph setting, Graph sets the type of graph for the top or left part of the split screen, and Graph 2 sets the bottom or right part. The available choices are the same as for Graph. Split Screen Ratio (Voyage 200 only) Specifies the proportional sizes of the two parts of a split screen. 1:1 The screen is split evenly. 1:2 The bottom or right part is approximately twice the size of the top or left part. 2:1 The top or left part is approximately twice the size of the bottom or right part.
