3-74 Full Command and Function Reference
•
x
min
and x
max
are real numbers that specify the input region's width. The default value is (–
1,1).
• y
min
and y
max
are real numbers that specify the input region's depth. The default value is (–1,1).
• x
eye
, y
eye
, and z
eye
are real numbers that specify the point in space from which you view the
graph.
• x
step
and y
step
are real numbers that set the number of x-coordinates versus the number of y-
coordinates plotted. These can be used instead of (or in combination with) RES.
The plotting parameters are specified in the reserved variable PPAR, which has the following form:
{ (x
min
, y
min
), (x
max
, y
max
), indep, res, axes, ptype, depend }
For plot type GRIDMAP, 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 GRIDMAP places
the command name GRIDMAP in PPAR.
• depend is a name specifying the dependent variable. The default value is Y.

→GROB
Type: Command
Description: Stack to Graphics Object Command: Creates a graphics object from a specified object, where the
argument n
char size
specifies the character size of the object.
n
char size
can be 0, 1 (small), 2 (medium), or 3 (large). n
char size
= 0 is the same as n
char size
= 3, except
for unit objects and algebraic objects, where 0 specifies the Equation Writer application picture.
