分组箱图Matlab [英] Grouping boxplot matlab

问题描述

我有x = rand(1000,6); y = rand(1000,6); D(:，1:2:12)= x; D(:，2:2:12)= y;

I have x=rand(1000,6); y=rand(1000,6); D(:,1:2:12)=x; D(:,2:2:12)=y;

我想绘制一个分组的boxplot，其中x(:，i)和y(:，i)是分组的箱线图(或因子对).但似乎无法找出如何指定分组.

I would like to plot a grouped boxplot where x(:,i) and y(:,i) are grouped boxplots (or factor pairs). But can't seem to work out how to specify the groupings.

因此:

figure('color',[1,1,1]);
boxplot(D,'factorgap',10,'color','rk')
axis([0 25 -1 5])

set(gca,'xtick',1.8:4.3:50)
set(gca,'ytick',0:10)
set(gca,'xticklabel',{'Direct care','Housekeeping','Mealtimes','Medication','Miscellaneous','Personal care'})

ylabel('Normalised Y');
 legend(findobj(gca,'Tag','Box'),'HBN04-01 multibed','YAB single ')

但是看起来有点不整洁，如何使成对的箱形图之间的间隙更大?

But it looks a bit untidy, how do I get the gaps between pairs of boxplots larger?

推荐答案

您需要一个双重分组变量:

You need a double grouping variable:

boxplot(D, {reshape(repmat('A':'F',2,1),12,1) repmat((1:2)',6,1)} ,'factorgap',10,'color','rk')

将标签居中非常不切实际，而且是噩梦般的.

Centering the labels is quite impractical and nightmerish.
