Option Meaning (Continued)

In Divides horizontal and vertical scales

by the X-factor and Y-factor. For

instance, if zoom factors are 4, then

zooming in results in 1/4 as many units

depicted per pixel, (see Set Factors)

Out Multiplies horizontal and vertical

scales by the X-factor and Y-factor

(see Set Factors).

X-Zoom In Divides horizontal scale only, using

X-factor.

X-Zoom Out Multiplies horizontal scale, using

X-factor.

Y-Zoom In

Divides vertical scale only, using

Y-factor.

Y-Zoom Out Multiplies vertical scale only, using

Y-factor.

Square Changes the vertical scale to match the

horizontal scale. (Use this after doing a

Box Zoom, X-Zoom, or Y-Zoom.)

Set

Factors...

Sets the X-Zoom and Y-Zoom factors

for zooming. Includes option to

recenter the plot before zooming.

Auto Scale Rescales the vertical axis so that the

display shows a representative piece of

the plot, for the supplied x axis

settings. (For Sequence and Statistics

aplets, autoscaling rescales both axes.)

The autoscale process uses the first

selected function only to determine the

best scale to use.

Decimal Rescales both axes so each pixel = 0.1

units. Resets default values for XRNG

(-6.5 to 6.5) and YRNG (-3.1 to 3.2).

(Not in Sequence or Statistics aplets.)
