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 FnOff ¸ Done PlotsOff ¸ Done {1,2,3,4}!L1 ¸ {1 2 3 4} {2,3,4,5}!L2 ¸ {2 3 4 5} NewPlot 1,1,L1,L2,,,,4 ¸ Done Press ¥ % to display: 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 NewProb ¸ Done 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
