I am facing the following problem with the legend of a plot that display
the mean and variance of a measurement y as a function of x, the mean
being represented by a dot and the variance by a vertical line.
My problem is that I am unable to display the symbol (dot + vertical
line) in the legend.
any help is welcome,
