I hope this helps:
/octave/3.4.3 is where I have my octave installed.
>>help boxplot
`boxplot' is a function from the file
/octave/3.4.3/packages/statistics-1.1.0/boxplot.m
-- Function File: S = boxplot (DATA, NOTCHED, SYMBOL, VERTICAL,
MAXWHISKER, ...)
Produce a box plot.
The box plot is a graphical display that simultaneously describes
several important features of a data set, such as center, spread,
departure from symmetry, and identification of observations that
lie unusually far from the bulk of the data.
DATA is a matrix with one column for each data set, or data is a
cell vector with one cell for each data set.
NOTCHED = 1 produces a notched-box plot. Notches represent a robust
estimate of the uncertainty about the median.
NOTCHED = 0 (default) produces a rectangular box plot.
NOTCHED in (0,1) produces a notch of the specified depth. notched
values outside (0,1) are amusing if not exactly practical.
SYMBOL sets the symbol for the outlier values, default symbol for
points that lie outside 3 times the interquartile range is 'o',
default symbol for points between 1.5 and 3 times the interquartile
range is '+'.
SYMBOL = '.' points between 1.5 and 3 times the IQR is marked with
'.' and points outside 3 times IQR with 'o'.
SYMBOL = ['x','*'] points between 1.5 and 3 times the IQR is
marked with 'x' and points outside 3 times IQR with '*'.
VERTICAL = 0 makes the boxes horizontal, by default VERTICAL = 1.
MAXWHISKER defines the length of the whiskers as a function of the
IQR (default = 1.5). If MAXWHISKER = 0 then `boxplot' displays all
data values outside the box using the plotting symbol for points
that lie outside 3 times the IQR.
Supplemental arguments are concatenated and passed to plot.
The returned matrix S has one column for each data set as follows:
1 Minimum
2 1st quartile
3 2nd quartile (median)
4 3rd quartile
5 Maximum
6 Lower confidence limit for median
7 Upper confidence limit for median
Example
title ("Grade 3 heights");
tics ("x", 1:2, {"girls"; "boys"});
axis ([0,3]);
boxplot ({randn(10,1)*5+140, randn(13,1)*8+135});
Additional help for built-in functions and operators is
available in the on-line version of the manual. Use the command
`doc <topic>' to search the manual index.
Help and information about Octave is also available on the WWW
at http://www.octave.org and via the h...@octave.org
mailing list.
