HP Prime Graphing NW280AAABA Shows a representative piece of the plot, Pixel equals 0.1 units

Option	Result (Cont.)
Square	Changes the vertical scale to match the
	horizontal scale. This is useful after you
	have done a box zoom, X zoom or Y
	zoom.
Autoscale	Rescales the vertical axis so that the display
	shows a representative piece of the plot
	given the supplied x axis settings. (For
	Sequence, Polar, parametric, and Statistics
	apps, autoscaling rescales both axes.)
	The autoscale process uses the first selected
	function to determine the best scale to use.
Decimal	Rescales both axes so each pixel is 0.1
	units. This is equivalent to resetting the
	default values for XRNG and YRNG.
Integer	Rescales the horizontal axis only, making
	each pixel equal to 1 unit.
Trig	Rescales the horizontal axis so that
	1 pixel equals π/24 radians or 7.5
	degrees; rescales the vertical axis so that 1
	pixel equals 0.1 units.
Undo Zoom	Returns the display to the previous zoom, or
	if there has been only one zoom, displays
	the graph with the original plot settings.
