MATLAB: Error bar from xlsx

Question

Hello

I have data from excel and I imported and everything going fine except error bar doesn't work

I have an error bar in column 3, this is the first time I use it.

Thank you in advance.

A=importdata('value.xlsx')
x=A.data(:,2)
b=A.data(:,1)
err=A.date(:,3)
S1=plot(x,b,err,'sk','MarkerFaceColor','k')
error(x,b,err)

Answer 1

The function to plot error bars is errorbar() not error()
