YRNG
Type: Command
Description: y-Axis Display Range Command: Specifies the y-axis display range.
The y-axis display range is stored in the reserved variable PPAR as y
min
and y
max
in the complex
numbers (x
min
, y
min
) and (x
max
, y
max
). These complex numbers are the first two elements of PPAR
and specify the coordinates of the lower left and upper right corners of the display ranges.
The default values of y
min
and y
max
are –3.1 and 3.2, respectively for the HP 48gII and -3.9
and 4.0, respectively for the HP 50g and 49g+.

YSLICE
Type: Command
Description: Y-Slice Plot Command: Sets the plot type to YSLICE.
When plot type is set YSLICE, the DRAW command plots a slicing view of a scalar function of
two variables. YSLICE requires values in the reserved variables EQ, VPAR, and PPAR.
VPAR has the following form:
{ x
left
, x
right
, y
near
, y
far
, z
low
, z
high
, x
min
, x
max
, y
min
, y
max
, x
eye
, y
eye
, z
eye
, x
step
, y
step
}
For plot type YSLICE, the elements of VPAR are used as follows:
•
x
left
and x
right
are real numbers that specify the width of the view space.
•
y
near
and y
far
are real numbers that specify the depth of the view space.
•
z
low
and z
high
are real numbers that specify the height of the view space.
•
x
min
and x
max
are not used.
•
y
min
and y
max
are not used.
•
x
eye
, y
eye
, and z
eye
are real numbers that specify the point in space from which the graph is
viewed.
•
x
step
determines the interval between plotted x-values within each “slice”.
•
y
step
determines the number of slices to draw.
The plotting parameters are specified in the reserved variable PPAR, which has this form:
{ (x
min
, y
min
), (x
max
, y
max
), indep, res, axes, ptype, depend }
For plot type YSLICE, the elements of PPAR are used as follows:
•
(x
min
, y
min
) is not used.
•
(x
max
, y
max
) is not used.
•
indep is a name specifying the independent variable. The default value of indep is X.
•
res is a real number specifying the interval, in user-unit coordinates, between plotted values of
the independent variable; or a binary integer specifying the interval in pixels. The default value is
0, which specifies an interval of 1 pixel.
•
axes is not used.
•
ptype is a command name specifying the plot type. Executing the command YSLICE places
YSLICE in ptype.
•
depend is a name specifying the dependent variable. The default value is Y.
