strange symbol instead of legend color

I am plotting a bar graph but it shows strange symbol instead of legend color.(All legend with title scoliosis)

Not enough info. A picture and/or some code would help.

[Osi fri]

Yes I have just added both ( code and a picture).

Thanks!

Those seem to me to be the legend entries for the errorbar plots.

The strange lines in the legend are the legend entries for the errorbar()

If you only want the bar() call to be legend'd then record the handles of the bar() and pass them to legend()
