A complex number specifying the upper right corner of
PICT (the upper right corner of the display range).
(6.5, 3.2) 48gII
(6.5, 4.0) 49g+
(6.5, 4.0) 50g
indep (INDEP) A name specifying the independent variable, or a list
containing that name and two numbers that specify the
minimum and maximum values for the independent
variable (the plotting range).
X
res (RES) Resolution. A real number specifying the interval
between values of the independent variable. For plots of
equations, this determines the plotting interval along the
x-axis. A binary number specifies the pixel resolution
(how many columns of pixels between points). An
integer specifies the resolution in user units (how many
user units between points). Resolution for statistical
plots is different (see below).
0
axes (AXES) A complex number specifying the user-unit coordinates
of the plot origin, or a list containing the following:
the complex number specifying the origin
a real number, binary integer, or list containing two
real numbers or binary integers specifying the tick-
mark annotation (see ATICK)
two strings specifying labels for the horizontal and
vertical axes
(0, 0)
ptype
(BAR, etc.)
A command name specifying the plot type (BAR,
CONIC, DIFFEQ, FAST3D, FUNCTION,
GRIDMAP, HISTOGRAM, PARAMETRIC,
PARSURFACE, PCONTOUR, POLAR, SCATTER,
SLOPEFIELD, TRUTH, WIREFRAME, or YSLICE).
FUNCTION
depend (DEPND) A name specifying the dependent variable, or a list
containing the name and two numbers that specify
vertical plotting range. For DIFFEQ, the second
element of the list may also be a real vector that
represents the initial value.
Y
Parameters without commands can be modified with a program by storing new values in the list contained in PPAR
(use the PUT command).
