Creates a new plot definition for plot number
n
.
type
specifies the type of the graph plot.
1 = scatter plot
2 = xyline plot
3 = box plot
4 = histogram
5 = modified box plot
mark
specifies the display type of the mark.
1 =
è
(box)
2 = × (cross)
3 = + (plus )
4 =
é
(square)
5 =
ø
(dot)
bucketSize
is the width of each histogram
“bucket” (
type
= 4), and will vary based on
the window variables
xmin
and
xmax
.
bucketSize
must be >0. Default = 1.
Note:
n
can be 1–9. Lists must be variable
names or c1–c99 (columns in the last data
variable shown in the Data/Matrix Editor),
except for
includeCatList
, which does not
have to be a variable name and cannot be
c1–c99.

NewProb
Performs a variety of operations that let you
begin a new problem from a cleared state
without resetting the memory.
•
Clears all single-character variable names
(
Clear a–z
) in the current folder, unless the
variables are locked or archived.
•
Turns off all functions and stat plots
(
FnOff
and
PlotsOff
) in the current
graphing mode.

nInt()
MATH/Calculus menu
nInt(
expression1, var, lower, upper
)
⇒
expression
If the integrand
expression1
contains no
variable other than
var
, and if
lower
and
upper
are constants, positive
ˆ
, or negative
ˆ
, then
nInt()
returns an approximation of
‰
(
expression1
,
var
,
lower
,
upper
)
. This
approximation is a weighted average of some
sample values of the integrand in the interval
lower<var<upper
.
