bars with mean and std on them

hi every body. i need to plot bar of 2 groups in x axis each containing 3 type of datas with mean and std on them. but i have error in the following code. could anybody help me please?

Y=[32.1 21.3 53.4;10.4 9.1 23.5];  %% mean values
X = categorical({'whole V','Proposed method'});
X = reordercats(X,{'whole V','Proposed method'});
Xv = 1:numel(X);                                                   
STD_low=[0.73 0.217 0.529;0.161 0.112 0.131]; %% standard deviations
STD_high=STD_low;
figure
b=bar(Xv,Y);                                                        
xtips1 = b(1).XEndPoints;
ytips1 = b(1).YEndPoints;
for k1 = 1:size(Y,2)
    ctr(k1,:) = bsxfun(@plus, b(k1).XData, b(k1).XOffset');         
    ydt(k1,:) = b(k1).YData;                                        
end

hold on
heb = errorbar(ctr, ydt, STD_low.', STD_high.', '.k');             
for k = 1:numel(heb)
    heb(k).MarkerSize = 1;
end
labels1 = string(b(1).YData);
text(xtips1,ytips1,labels1,'HorizontalAlignment','right',...
    'VerticalAlignment','bottom')
xtips2 = b(2).XEndPoints;
ytips2 = b(2).YEndPoints;
labels2 = string(b(2).YData);
text(xtips2,ytips2,labels2,'HorizontalAlignment','right',...
    'VerticalAlignment','bottom')

  
xticklabels(X)
legend('MAD', 'HD','DSC');

xlabel('Method of best match slice achievement') 
ylabel('Mean&Standard deviation (mm)')

replace the XEndPoints/YEndPoints by XData(end)/YData(end):

xtips1 = b(1).XData(end);

ytips1 = b(1).YData(end);

Btw, xticklabels(X) won't work. Either set xticklabels('auto') or xticklabels(b(1).XData)
