Graph Analysis Tool Graph Screen Operations

Key Operation

Description

Displays the graph relation list, which lets you select a Y=f(x)

K5(Y=fx)graph to overlay on the sampled result graph. See “Overlaying a Y=f(x) Graph on a Sampled Result Graph” on page ε-45.

Starts an operation for outputting a specific range of a sound data

K6(SPEAKER) waveform graph from the speaker. See “Outputting a Specific Range of a Graph from the Speaker” on page ε-48.

kScrolling the Graph Screen

Press the cursor keys while the graph screen is on the display scrolls the graph left, right, up, or down.

Note

The cursor keys perform different operations besides scrolling while a trace or graph operation is in progress. To perform a graph screen scroll operation in this case, press J to cancel the trace or graph operation, and then press the cursor keys.

kUsing Trace

Trace displays a crosshair pointer on the displayed graph along with the coordinates of the current cursor position. You can use the cursor keys to move the pointer along the graph. You can also use trace to obtain the periodic frequency value for a particular range, and assign the range (time) and periodic frequency values in separate Alpha memory variables.

• To use trace

1.On the graph screen, press !1(TRACE).

This causes a trace pointer to appear on the graph. The coordinates of the current trace pointer location are also shown on the display.

2.Use the d and e cursor keys to move the trace pointer along the graph to the location you want.

The coordinate values change in accordance with the trace pointer movement.

You can exit the trace pointer at any time by pressing J.

• To obtain the periodic frequency value

1.Use the procedure under “To use trace” above to start a trace operation.

2.Move the trace pointer to the start point of the range whose periodic frequency you want to obtain, and then press w.
