Decimal scaling
Decimal scaling is the default scaling. If you have
changed the scaling to Trig or Integer, you can change it
back with Decimal.
Integer scaling
Integer scaling compresses the axes so that each pixel is
and the origin is near the screen center.
Trigonometric
scaling
Use trigonometric scaling whenever you are plotting an
expression that includes trigonometric functions.
Trigonometric plots are more likely to intersect the axis at
points factored by
π
.
