bars are stacked instead of grouped while 'grouped'

hi guys, does anybody maybe know why my bars keep being stacked instead of grouped??

qual = readmatrix('qualtrics_srec.txt');
qual_jong = readmatrix('qualtrics_srec_jong.txt');
qual_oud = readmatrix('qualtrics_srec_oud.txt');


figure
bar(qual(57,3:14),'grouped')
hold on
bar(qual_jong(29,3:14),'grouped')
bar(qual_oud(29,3:14),'grouped')

To group the bars, use something like this:

qual = rand(57);
qual_jong = rand(29);
qual_oud = rand(29);
d = [qual(57,3:14); qual_jong(29,3:14); qual_oud(29,3:14)];

figure
bar(d); % or use d' depending on the desired grouping

The 'grouped' modifier has no effect in your code because the data in each bar function are just a vector.
