I am trying to add error bars to bar graph. The figure looks fine if I run it without the error bars as just bar(coh). (see attached) I want to the bars to be groups as shown. I'm wondering if that grouping is messing up the error bars.

Thank you in advance for any help!

Hope you are all staying safe and healthy Matlab community.

x = 1:12;
coh = [0.9862, 0.9773
       0.971,  0.9544
       0.8969, 0.6791
       0.8835, 0.9051
       0.8558, 0.6727
       0.6727, 0.8641]; 
errhigh = [0.0083, 0.0137  
           0.0137, 0.0274 
           0.0611, 0.1797 
           0.0688, 0.0563 
           0.1426, 0.1829 
           0.0875, 0.0799];
errlow  = [0.0208, 0.034
           0.043,  0.0661 
           0.1382, 0.3105
           0.1533, 0.1288
           0.1827, 0.3135
           0.1879, 0.1743];   
   
figure
bar(x,coh)
%bar(coh)
hold on 
er = errorbar(x,coh,errlow,errhigh);    
er.Color = [0 0 0];                            
er.LineStyle = 'none';  
hold off

In 40 years, TMW has yet to provide any decent hatching... :(

There are some submissions on File Exchange; all that I've used have warts of various severity; and whether any will work with bar I've never tried/looked.
