11 Graph Analysis Tool Graph Screen Operations

This section explains the various operations you can perform on the graph screen after
drawing a graph.
You can perform these operations on a graph screen produced by a sampling operation, or by the
operation described under "Selecting an Analysis Mode and Drawing a Graph" on page 10-1.
k Graph Screen Function Key Operations
When a graph screen is on the display, the function keys provide you with the following
operations, which are indicated by the function menu along the bottom of the screen.
Press function key 6( g ) to toggle between Function Menu 1 and Function Menu 2.
The following tables describe the functions that are available from each of the function menus.

Function Menu 1
Displays a trace pointer on the graph along with the coordinates of the
current cursor location. Trace can also be used to obtain the periodic
frequency of a specific range on the graph and assign it to a variable.
See "Using Trace" on page 11-2.
Starts a zoom operation, which you can use to enlarge or reduce the
size of the graph along the
page 11-3.
Displays a menu that contains the following commands: Cls, PlotOn,
PlotOff, PlotChange, Text, Vert, and Horz. For details about each
command, see "5-10 Changing the Appearance of a Graph" in the
manual that comes with the ALGEBRA FX2.0/FX1.0 calculator.
Displays a menu that lets you transform a sample result graph to a
function using Fourier series expansion, and to perform regression to
determine the tendency of a graph. See "Using Fourier Series Expansion
to Transform a Waveform to a Function" on page 11-5, and "Performing
Regression" on page 11-7.
Displays the graph function list, which lets you select a Y=f(x) graph to
overlay on the sampled result graph. See "Overlaying a Y=f(x) Graph on
a Sampled Result Graph" on page 11-8.
