Type: Command

Description: Autoscale Command: Calculates a yaxis display range, or an x and yaxis 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 xaxis plotting range, discards
	points that return ±∞, then sets the yaxis display range to include
	the maximum, minimum, and origin.
CONIC	Sets the yaxis scale equal to the xaxis 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 yaxis display
	ranges in the same manner as for plot type FUNCTION.
PARAMETRIC	Same as POLAR.
TRUTH	No action.
BAR	Sets the xaxis display range from 0 to the number of element s in
	ΣDAT, plus 1. Sets the yrange to the minimum and maximum of
	the elements. The xaxis is always included.
HISTOGRAM	Sets the xaxis display range to the minimum and maximum of
	the elements in ΣDAT. Sets the yaxis display range from 0 to the
	number of rows in ΣDAT.
SCATTER	Sets the xaxis 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 yaxis 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 yaxes, tickmark annotation, and the labels for the x and yaxes. This information is stored in the reserved v ariable PPAR.
