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 10-2.

kGraph Screen Key Operations

On the graph screen, you can use the keys described in the table below to analyze (CALC) graphs by reading data points along the graph (Trace) and enlarging specific parts of the graph (Zoom).

Key Operation

Description

 

 

 

Displays a trace pointer on the graph along with the coordinates of the

!1(TRCE)

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 11-3.

 

 

 

Starts a zoom operation, which you can use to enlarge or reduce the

!2(ZOOM)

size of the graph along the x-axis or the y-axis. See “Using Zoom” on

 

page 11-4.

 

 

 

Displays a function menu of special View Window commands for the

!3(V-WIN)

E-CON2 Mode graph screen.

For details about each command, see “Configuring View Window

 

 

Parameters” on page 11-14.

 

 

 

Displays a menu that contains the following commands: Cls, Plot,

!4(SKTCH)

F-Line, Text, PEN, Vert, and Hztl. For details about each command, see

 

“5-10 Changing the Appearance of a Graph” in the manual that comes

 

with the fx-9860G SD/fx-9860G calculator.

 

 

 

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.

K1

For details about these procedures, see “5-4 Storing a Graph in Picture

(PICT)

Memory” in the manual that comes with the fx-9860G SD/fx-9860G

 

 

calculator.

 

 

 

Displays a menu of functions for saving the sample values in a specific

K2

range of a graph to a list. See “Transforming Sampled Data to List Data”

(LMEM)

on page 11-5.
