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.)
