Type: Command

Description: Autoscale Command: Calculates a y-axis display range, or an x- and y-axis display range. The action of AUTO depends on the plot type as follows:

Plot Type	Scaling Action
FUNCTION	Samples the equation in EQ at 40 values of the independent
	variable, equally spaced through the x-axis plotting range, discards
	points that return ±∞, then sets the y-axis display range to include
	the maximum, minimum, and origin.
CONIC	Sets the y-axis scale equal to the x-axis scale.
POLAR	Samples the equation in EQ at 40 values of the independent
	variable, equally spaced through the plotting range, discards
	points that return ±∞, then sets both the x- and y-axis display
	ranges in the same manner as for plot type FUNCTION.
PARAMETRIC	Same as POLAR.
TRUTH	No action.
BAR	Sets the x-axis display range from 0 to the number of elements in
	ΣDAT, plus 1. Sets the y-range to the minimum and maximum of
	the elements. The x-axis is always included.
HISTOGRAM	Sets the x-axis display range to the minimum and maximum of
	the elements in ΣDAT. Sets the y-axis display range from 0 to the
	number of rows in ΣDAT.
SCATTER	Sets the x-axis display range to the minimum and maximum of
	the independent variable column (XCOL) in ΣDAT. Sets the y-
	axis display range to the minimum and maximum of the
	dependent variable column (YCOL).

AUTO does not affect 3D plots.

AUTO actually calculates a y-axis display range and then expands that range so that the menu labels do not obscure the resultant plot.

AUTO does not draw a plot — execute DRAW to do so.

AXES

Type: Command

Description: Axes Command: Specifies the intersection coordinates of the x- and y-axes, tick-mark annotation, and the labels for the x- and y-axes. This information is stored in the reserved variable PPAR.
