NewPlot CATALOG
NewPlot n , type , xList [ , [ yList ], [ frqList ], [ catList ],
[ includeCatList ], [ mark ] [, bucketSize ]]
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 CATALOG
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.
• Perfoms ClrDraw , ClrErr , ClrGraph ,
ClrHome , ClrIO , and ClrTable .

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 .
