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
, x
left
right
For plot type YSLICE, the elements of VPAR are used as follows:
• x
and x
left
• y
and y
near
• z
and z
low
• x
and x
min
• y

viewed.
• x
determines the interval between plotted x-values within each "slice".
step
• y
determines the number of slices to draw.

The plotting parameters are specified in the reserved variable PPAR, which has this form:
For plot type YSLICE, the elements of PPAR are used as follows:
• (x
, y
min
• (x
, y
max
• 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.
