HP 40G manual About the numeric view, Overlay plots, Decimal scaling

Overlay plots	If you want to plot over an existing plot without erasing that
	plot, then use >9,(:6@ Overlay Plot instead of >3/27@.
	Note that tracing follows only the current functions from the
	current aplet.
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

Trigonometric scaling

Integer scaling compresses the axes so that each pixel is 1 ⋅ 1 and the origin is near the screen center.

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.

About the numeric view

After entering and selecting (check marking) the expression or expressions that you want to explore in the Symbolic view, press >180@ to view a table of data
