I just used the example from doc,

x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
err = 8*ones(size(y));
errorbar(x,y,err)

However, the figure has no connecting lines, unlike the documentation:

What version of the documentation did you use? The current online documentation is for R2016b, and that code works correctly for me (connects the centres of the bars with a line, and plotting the error bars) in R2016b.

Type:

doc errorbar

in your Command Window to get the documentation for your version. There could be version differences.

It is fixed in R2016b.

Or after you plot it you could try

set(gca,'linestyle','--')

thanks for the following up. I can't reproduce my original problem on another computer, so I guess something was wrong with my setup. Luckily after updating my Matlab to 2016b it fixed itself.
