Boxplots in the same figure

Hi everyone

How can I compaine two boxplots in the same figure for this code?

figure
sgtitle('main graph')
subplot(1,2,1);
boxplot(X,'first')
ylabel('timer')
grid on
subplot(1,2,2);
boxplot(Y,'Second')
ylabel('timer')
grid on

I've tried used solution in below link but still I have problem:

https://uk.mathworks.com/help/stats/boxplot.html

I've tried:

figure
hold on
x=[X;Y];
boxplot(x(1,:),'first')
boxplot(x(2,:),'secondl')
hold off
ylabel('timer')
title('main graph') 

also I've tried this solution but still there are error

= [16 20 15 17 22 19 17]';
B = [22 15 16 16 16 18]';
C = [23 9 15 18 13 27 17 14 16 15 21 19 17]';
group = [    ones(size(A));
    2 * ones(size(B));
    3 * ones(size(C))];
figure
boxplot([A; B; C],group)
set(gca,'XTickLabel',{'A','B','C'})

Welcome to the forum @NOUF ALHARBI. I've formatted your code using the the rich text editor but I haven't changed any of it. You'll notice some errors in red which are probably copy-paste errors.

Anyway, it's unclear how you would like to combine the boxplots and how many are in each group. An image would be nice, or at least a description.

Using a grouping variable is one option. Another option is using the "positions" property.

Hi Adam thank you so much,

I've two array I can put them in subplot as boxplot but I need to put it them in the same figue.

[Adam Danz]

Thanks, but it's still not clear. Let's say subplot A has 3 boxs and subplot B has 3 boxs. Do you want

[AB AB AB] or [ABABAB]

or

[AAA BBB] or [AAABBB]?

Subplot A has 1 box and subplot B has 1 box so just I want [A B]

but apeared to me like this:

Method 1: set position along x-axis

Use the positions property in boxplot to set the box x-coordinates.

A = rand(10,1); 
B = rand(8,1);

hold on
boxplot(A, 'Positions', 1)
boxplot(B, 'Positions', 2)
% Set desired xtick, xticklabels, and xlim
set(gca,'XTickMode','auto','XTickLabelMode','auto','XLimMode','auto')

Method 2: Combine columns of data

Vectors must have the same length. Pad shorter vectors with NaN values to equate lengths, if necessary.

A = rand(10,1); 
B = rand(10,1); 

data = [A(:),B(:)];
figure
boxplot(data)

Many thanks Adam Danz, but how can I change names in x-coordinates? I want right the name of each .

I used this

A = rand(10,1);

B = rand(8,1);

hold on

boxplot(A, 'Positions', 1)

boxplot(B, 'Positions', 2)

% Set desired xtick, xticklabels, and xlim

set(gca,'XTickMode','auto','XTickLabelMode','auto','XLimMode','auto')

[Adam Danz]

For method 1

set(gca,'XTick',1:2,'XTickLabel',{'Group 1', 'Group 2'},'XLim', [0.5,2.5])

For method 2

boxplot(data,'labels',{'Group1','Group2'})

Many thanks Adam Danz
