hey,

i have tried a few of the other answers to similar problems however i come into an issue where the error bars are all drawn together.

here is my code, any advice would be helpful

i am using matlab 2018a

% my data is WUSW, the group labels are X, the errors are WerrL & WerrH
% respectively
WUSW = [0.22 0.18;0.21 0.08; 0.22 0.14; 0.25 0.13];
 X = categorical({'Flat','Lotus','Lines','Sharklet'});
 X = reordercats(X,{'Flat','Lotus','Lines','Sharklet'});
 WerrL = [0.01 0.06 0.03 0.06; 0.03 0.04 0.04 0.02];
 WerrH = [0.02 0.03 0.03 0.04; 0.03 0.03 0.03 0.06];
 %here is the code i adapted from the other answers to problems 
 figure
hBar = bar(WUSW, 0.8);                                                     % Return ‘bar’ Handle
for k1 = 1:size(WUSW,2)
    ctr(k1,:) = bsxfun(@plus, hBar(k1).XData, hBar(k1).XOffset');       % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
    ydt(k1,:) = hBar(k1).YData;                                         % Individual Bar Heights
end
hold on
errorbar(ctr, ydt, WerrL, WerrH)
%when i do this all the error bars display correctly but are connected like
%a daisy chain
