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.
