2-10 Aplets and their views

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 in or zooming out.

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.)

Integer Rescales horizontal axis only,

making each pixel =1 unit. (Not

available in Sequence or Statistics

aplets.)

Trig Rescales horizontal axis so

1 pixel = π/24 radians, 7.58, or

8

1

/

3

grads; rescales vertical axis

so

1 pixel = 0.1 unit.

(Not in Sequence or Statistics

aplets.)
