Display of errorbar function in plot legend

Hi

I am annoyed about a line going through the errorbar symbol in my legend. I have tried to make a dummy plot for handles, ploting it prior to all other plots with lines in them, but it does not change anything. I can not find any information about it in the documentation and I was not able to find any other treads where this was complained about and obviously not any solution either. I attached an image below since it is a bit hard to explain. Thanks a lot!

This is how I ploted the errorbar

errorbar(mean(x1),mean(y1),sdy1,sdy1,sdx1,sdx1,'k')
