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

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.

(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.

Memory” under Chapter 5 of this manual.

K 2
