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.
