k Scrolling the Graph Screen
Press the cursor keys while the graph screen is on the display scrolls the graph left, right, up,
or down.
Note
• The cursor keys perform different operations besides scrolling while a trace or graph
operation is in progress. To perform a graph screen scroll operation in this case, press
i to cancel the trace or graph operation, and then press the cursor keys.
k Using Trace
Trace displays a crosshair pointer on the displayed graph along with the coordinates of the
current cursor position. You can use the cursor keys to move the pointer along the graph. You
can also use trace to obtain the periodic frequency value for a particular range, and assign
the range (time) and periodic frequency values in separate Alpha-Memory values.

u To use trace
1. On the graph screen, press 1(TRACE).
• This causes a trace pointer to appear on the graph. The coordinates of the current trace
pointer location are also shown on the display.

Saves the currently displayed graph as a graphic image. You can recall a
saved graph image and overlay it on another graph to compare them.
For details about these procedures, see “5-4 Storing a Graph in Picture
Memory” in the manual that comes with the ALGEBRA FX2.0/FX1.0
calculator.
Displays a menu of functions for zooming and editing a particular graph
when the graph screen contains multiple graphs. See “Working with
Multiple Graphs” on page 11-9.
Starts an operation for outputting a specific range of a sound data
waveform graph from the speaker. See “Outputting a Specific Range of a
Graph from the Speaker” on page 11-11.
