boxplot2.m: Alternative Matlab boxplots

Author: Kelly Kearney View boxplot2 on File Exchange

This repository includes the code for the boxplot2.m Matlab function, along with all dependent functions required to run it. This function is intended as an alternative to the boxplot.m function that is included in the Statistics and Machine Learning Toolbox.

The original boxplot.m function is more heavy-handed than most Matlab plotting functions; it replaces ticks with text labels, changes axis dimensions, etc. This version creates a boxplot with a minimal amount of alteration to existing axes, assuming that any cosmetic changes (color, tick labels, line specs, etc) can be added by the user afterwards if necessary.

Additionally, this function allows one to create clustered boxplots, similar to an unstacked bar graph. See below for an example.

Getting Started

Prerequisites

This software requires Matlab (tested primarily on R2012a-R2016a), as well as the Statistics and Machine Learning Toolbox.

Dowloading

Git users can clone (or fork, then clone) directly from this repository.

Alternatively, you may download a zipped version of this code either from this page or from the boxplot2.m entry on the MatlabCentral FileExchange. The File Exchange entry is updated daily from this repository.

Installation

Once downloaded (and unzipped, if necessary), all subfolders in the main folder need to be added to your Matlab path:

% Replace with location of the downloaded folder
pth = './boxplot2-pkg/';

addpath(fullfile(pth, 'boxplot2'); 
addpath(fullfile(pth, 'minmax'); 

Usage

Syntax

h = boxplot2(y)
h = boxplot2(y,x)
h = boxplot2(..., p1, v1, ...)

See standard function headers (accessed via doc or help) for a full description of input and output variables.

Example

This example demonstrates how to create a simple grouped boxplot, and then to change some of the cosmetic details:

% Data

x = 1:5;
y = randn(5, 3, 100);

% Plot boxplots

h = boxplot2(y,x);

% Alter linestyle and color

cmap = get(0, 'defaultaxescolororder');
for ii = 1:3
    structfun(@(x) set(x(ii,:), 'color', cmap(ii,:), ...
        'markeredgecolor', cmap(ii,:)), h);
end
set([h.lwhis h.uwhis], 'linestyle', '-');
set(h.out, 'marker', '.');
