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.
k Graph 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
!1
(TRCE)
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 11-3.
!2
(ZOOM)
Starts a zoom operation, which you can use to enlarge or reduce the
size of the graph along the x-axis or the y-axis. See “Using Zoom” on
page 11-4.
!3(V-WIN)

Displays a menu that contains the following commands: Cls, Plot,
F-Line, Text, PEN, Vert, and Hztl. For details about each command,
see “5-10 Changing the Appearance of a Graph” under Chapter 5 of
this manual.
K1
( PICT )
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” under Chapter 5 of this manual.
K2
( LMEM )
Displays a menu of functions for saving the sample values in a specific
range of a graph to a list. See “Transforming Sampled Data to List
Data” on page 11-5.

when the graph screen contains multiple graphs. See “Working with
Multiple Graphs” on page 11-10.
