How to add another plot to box plot?

I need to make plot like this:

I know how to plot each individually but dont know how to plot them next to each other like the image.

inlcude the code that produces the box plots you want to merge please.

Hint:

hold on
bar(. . .)
plot(1.25, y, 'ko')
errorbar(. . .)

@Philippe Lebel

it is simply like this:

boxplot(T{(find_groups == No_class_images(k)),var(i)},'widths',0.1)

@Adam Danz

Thanks I tried it like what you mentioned before but it did not work.

[Zeynab Mousavikhamene]

@Walter Roberson any suggestion?

[Adam Danz]

Sure it does,

What did you try and what didn't work?

@Adam Danz

I tried

figure (1)
boxplot(y)
hold on
plot(2,y)
hold off

but it did not work.

I used 2 in x-axis of the second plot because the default for boxplot's x-axis is 1 (you can see in the image) so I tried to be next to the boxplot.

" it did not work" doesn't tell me much.

Here are some more tips.

• y should be a vector.
• Specify black circle markers using 'ko'.
• you still need to use errorbar() if you want the magenta errorbar.

As I said in the question, each plot is produced individually so the points mentioned above (being vector, using 'ko',...) does not change the issue I have.

Yes 'it did not work' is not clear. Let me tell more about it: Using above code the boxplot was produced but the nex plot (the plot after hold on) was not shown. it was only boxplot.

" so the points mentioned above (being vector, using 'ko',...) does not change the issue I have"

It's hard to address the issue you're having when you haven't explained what the issues are.

This line from your code plot(2,y) will definitely not produce the plot you want since it will produce lines, not black circular markers. So the 'ko' does address that problem. If y were a matrix, it would also produce undesired effects which is why y must be a vector - but again, we don't know what the issues are.

'Using above code the boxplot was produced but the nex plot (the plot after hold on) was not shown"

Ahhhh... there we go. The points created by plot() are plotted but you just can't see them.

Here's your fix:

xlim([0,3])

@Adam Danz

xlim worked. Thank you. Can you move your comment to answers so that I can accept?

Summary of comments under the question

The problem was that the x axis limit was [0,1] while the plotted data were at x=2.

The solution:

xlim([0,3])
