k k k k k About Dual Graph Screen Types
The screen on the left side of the display is called the active screen, and the graph
on the left side of the display is called the active graph. Conversely, the right side
is the inactive screen, which contains the inactive graph. Any function that you
execute while using Dual Graph is always applied to the active graph. To execute
a function on the right-side inactive graph, you must first make it active by moving
it into the active screen.
Active Screen
Actual graph drawing is done here.
Inactive Screen
Use the inactive screen to make copies of active screen graphs, and for the result of
Zoom operations.
• Indicators appear to the right of the formulas in the function memory list to tell
where graphs are drawn with Dual Graph.
Indicates inactive 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 (inactive) side on the display.
The function marked “
B ” is drawn on both sides of the graph.
Pressing 1 (SEL) while one of the function’s is highlighted would causes its
“
R ” or “ B ” indicator to be cleared. A function without an indicator is drawn as
the active graph (on the left side of the display).
