Hello,

I would like to create an errorbar with each column of "test" represents a state (Base value, preperation value, test value, rest value)

test =
    0.8003    0.9157    0.6557    0.9340
    0.1419    0.7922    0.0357    0.6787
       NaN    0.9595    0.8491    0.7577
       
test_SE=nanstd(test)/sqrt(length(test))
test_SE =
    0.2328    0.0434    0.2125    0.0653
    
states =
  1×4 cell array
    {'Base'}    {'Preperation'}    {'Testing'}    {'Resting'}

If I try to do it with a boxplot it works perfecty // boxplot(test,states) //. But unfortunately I can' find a way to do it with errorbars.

I would be very thankful if somebody could help me out

Hi Max,

My understanding of your question is that you aren’t able to plot an errorbar with each column of your numerical data (Y axis) being a unique categorical column. While the errorbar in itself doesn’t let you perform this, there’s a workaround that you can try which might help in solving your issue.
