Graph Analysis Tool Graph Screen Operations

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 ε-36.

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

!1(TRACE)

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 ε-40.

 

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

!2(ZOOM)

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

 

Zoom” on page ε-41.

 

 

 

Displays a function menu of special View Window commands for

!3(V-WIN)

the E-Con2mode graph screen.

For details about each command, see “Configuring View Window

 

 

Parameters” on page ε-49.

 

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

!4(SKETCH)

F-Line, Text, PEN, Vertical, and Horizontal. For details about

each command, see “Drawing Dots, Lines, and Text on the Graph

 

 

Screen (Sketch)” on page 5-50.

 

 

 

Saves the currently displayed graph as a graphic image. You can

K1(PICTURE)

recall a saved graph image and overlay it on another graph to

compare them. For details about these procedures, see “Saving

 

 

and Recalling Graph Screen Contents” on page 5-20.

 

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

K2(LISTMEM)

specific range of a graph to a list. See “Transforming Sampled

 

Data to List Data” on page ε-42.

 

Displays a menu of functions for zooming and editing a particular

K3(EDIT)

graph when the graph screen contains multiple graphs. See

 

“Working with Multiple Graphs” on page ε-46.

 

 

 

Displays a menu that lets you transform a sample result graph to a

 

function using Fourier series expansion, and to perform regression

K4(CALC)

to determine the tendency of a graph. See “Using Fourier Series

 

Expansion to Transform a Waveform to a Function” on page ε-43,

 

and “Performing Regression” on page ε-44.
