Here's how to locate the center of each grouped bar and label them. It uses an undocumented property "XOffset". This was developed and tested in r2019a.
xCnt are the bar centers.
% Generate grouped bar plot
figure()
v = randi(20,12,3);
h = bar(v,.8);
% Get group centers
xCnt = get(h(1),'XData') + cell2mat(get(h,'XOffset')); % XOffset is undocumented!
% Create Tick Labels
xLab = repmat({'p1','p2','p3'},1,numel(xCnt)/3);
% Set individual ticks
set(gca, 'XTick', sort(xCnt(:)), 'XTickLabel', xLab)
Alternatively, you could rotate the x tick labels
set(gca, 'XTick', sort(xCnt(:)), 'XTickLabel', xLab, 'xticklabelrotation', 90)
% Or use xtickangle(): https://www.mathworks.com/help/matlab/ref/xtickangle.html
The best solution would be to use a legend
legend(h,{'p1','p2','p3'})

Hi Ali,
Here is a simple solution to your problem:
A= randi([15, 25], 13, 3); % Insert your data here
H = bar(A); shg
H(1).FaceColor='g';
H(2).FaceColor='r';
H(3).FaceColor='b';
Good luck.

Cool function, but how does that address the question of how to label the bar groups?
