AUTO
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.
