Did you try

legend('A','B','C')

???

This doesn't seem to work with bar.

How so?

bar(randi(400,4,3),'stacked')
legend('A','B','C')

I have the same problem and the code

bar(randi(400,4,3),'stacked')
legend('A','B','C')

gives me the error: Index in position 1 exceeds array bounds. Index must not exceed 11.

The bars are plotted as they should, but the legend won't appear.

I am using R2022a.

Help would be much appreciated.

edit:

Directly after posting this I found the error. I was using a variable called 'legend' in another script which was in the workspace. Changed it to something else, no it works fine. Wanted to share this stupid mistake, maxbe I am not the only one.

The piece of code you shared works here without any error, see below.

Share the full error message i.e. all of the red text.

Edit - This should be a (gentle) reminder to not name variables or scripts with the same as in-built functions in MATLAB.

bar(randi(400,4,3),'stacked')
legend('A','B','C')
