Hello,

I create a simple ggplot that only shows a straight line. I then add three
datasets of CI using the geom_errorbar function. The problem is that I can't
find any way to have the legend showing up ... I need to show what each  color
of the CIs corresponds to i.e. which method.

Can anyone advice please?
TIA,
Best regards,
Giovanni
