The Plot Sub-Menu - HP 49g+ User Manual

The functions available are the following:
TOT: show sum of each column in ΣDATA matrix.
MEAN: shows average of each column in ΣDATA matrix.
SDEV: shows standard deviation of each column in ΣDATA matrix.
MAXΣ: shows maximum value of each column in ΣDATA matrix.
MINΣ: shows average of each column in ΣDATA matrix.
, ∆x, n [BINS], provides frequency distribution for data in
BINS: used as x
s
Xcol column in ΣDATA matrix with the frequency bins defined as
[x ,x +∆x], [x ,x +2∆x],..., [x
s s s s
VAR: shows variance of each column in ΣDATA matrix.
PSDEV: shows population standard deviation (based on n rather than on (n-1))
of each column in ΣDATA matrix.
PVAR: shows population variance of each column in ΣDATA matrix.
MINΣ: shows average of each column in ΣDATA matrix.

The PLOT sub-menu

The PLOT sub-menu contains functions that are used to produce plots with the
data in the ΣDATA matrix.
The functions included are:
BARPL: produces a bar plot with data in Xcol column of the ΣDATA matrix.
HISTP: produces histogram of the data in Xcol column in the ΣDATA matrix,
using the default width corresponding to 13 bins unless the bin size is
modified using function BINS in the 1VAR sub-menu (see above).
SCATR: produces a scatterplot of the data in Ycol column of the ΣDATA
matrix vs. the data in Xcol column of the ΣDATA matrix. Equation
fitted will be stored in the variable EQ.
