Add column E as labels over the bars

% Set up the problem by recreating the table.
A = [ '0' '0' '1' '1' '2' '2' '3' '3']'; %%%%%%%%%%%%%%%
B = ['0' '1' '0' '1' '0' '1' '0' '1']';
C = [2 11 32 33 38 31 47 39]';
D = [0.5 0.7 9.5 3.3 3.8 3.1 4.7 3.9]';
E = ["Q1" "Q2" "Q1" "Q4" "Q1" "Q1" "Q2" "Q1"]';
T = table(A,B,C,D,E);
% use sortrows to organize data in an expected format
T = sortrows(T,["B","A"]);
% extract x values, group names
x = str2num(unique(T.A)); %%%%%%%%%%%%%%%%%
b = unique(T.B);
% Reshape the data based on the number of unique values in A
CC = reshape(T.C,length(x),[]);
DD = reshape(T.D,length(x),[]);
EE = reshape(T.E,length(x),[]);
% plot
hold on
hb = bar(x,CC)
errorbar(x-0.15,CC(:,1),DD(:,1),'o','Color','k') %%%%%%%%%%%%%%
errorbar(x+0.15,CC(:,2),DD(:,2),'o','Color','k') %%%%%%%%%%%%%%
% legend(b)
% xtips2 = hb(2).XEndPoints;
% ytips2 = hb(2).YEndPoints;
% labels2 = string(EE(2).YData);
%
% text(xtips2,ytips2,labels2,'HorizontalAlignment','center',...
% 'VerticalAlignment','bottom')
barWidth = hb.BarWidth;
numCol = size(CC,1);
cnt = 0;
for ii = EE'
cnt = cnt + 1;
xPos = linspace(cnt - barWidth/2, cnt + barWidth / 2, numCol+1);
idx = 1;
for jj = xPos(1:end-1)
val = EE(cnt,idx);
y = M(cnt,idx);
text(jj, y + 1, num2str(val));
idx = idx +1;
