AVERAGE different visualization?

[#1]

I currently have a barchart with the average lines over the year (See image).

But i have some questions related to this average, I'm pretty new to qlikview.

- Is there a way to have the same colors for all averages.

- Is there another way of visualizing this average number? Like when hovering over the average line that it shows a average, a white background color with 50% trancparency or something else that makes it better readable? Now it is unreadable. Maybe even with a symbol? But I'm unable to check Symbol in my Bar Chart Expression settings.
