Plot view settings, Θrng, Θstep | HP 39g+ Graphing instruction

Plot view settings

The plot view settings are:

Field	Meaning

XRNG, YRNG	Specifies the minimum and
	maximum horizontal (X) and
	vertical (Y) values for the plotting
	window.
RES	For function plots: Resolution;
	“Faster” plots in alternate pixel
	columns; “Detail” plots in every
	pixel column.
TRNG	Parametric aplet: Specifies the t-
	values (T) for the graph.
θRNG	Polar aplet: Specifies the angle (θ)
	value range for the graph.
NRNG	Sequence aplet: Specifies the
	index (N) values for the graph.
TSTEP	For Parametric plots: the increment
	for the independent variable.
θSTEP	For Polar plots: the increment
	value for the independent
	variable.
SEQPLOT	For Sequence aplet: Stairstep or
	Cobweb types.
XTICK	Horizontal spacing for tickmarks.
YTICK	Vertical spacing for tickmarks.

Those items with space for a checkmark are settings you

can turn on or off. Press to display the second page.

Field	Meaning

SIMULT	If more than one relation is being
	plotted, plots them simultaneously
	(otherwise sequentially).
INV. CROSS	Cursor crosshairs invert the status
	of the pixels they cover.

2-6	Aplets and their views
