Dual Graph

Dual Graph lets you split the display between two different
screens, which you can then use to draw different graphs at the
same time. Dual Graph gives you valuable graph analysis
capabilities.

•You should be familiar with the contents of “8-3 Graph Function
Operations” before reading this chapter.

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).
