The following illustration shows these relationships.
The split screen is always in the trace mode. Therefore, the
cursor pointer appears on the graph. Accordingly, the coordi-
nate values are displayed reverse in the table and in the
equation at which the cursor pointer is located is also displayed
reversely.
Using ; or ', move the cursor along the graph.
(Values displayed reverse in the table are also changed
accordingly.)
When two or more graphs are displayed on the screen, the
desired graph is selected using { or }. (The table or
equation on the right of the screen is also changed accordingly.)
The table on the split screen does not relate to the table
settings on the full-screen table.
The table on the split screen is displayed in units of trace
movement amount based on the cursor pointer position on the
graph screen. When the full-screen table is displayed by
pressing T, a different table may appear on the screen.
When the EXPRES or Y’ is set to ON on the FORMAT menu,
the equation or coordinates are displayed on the graph screen.
Only equations to be graphed are displayed on the split screen.
Press G or T on the split screen to display the full-
screen of the graph or table. To exit the split screen, press any
of other function keys.
