pgfplots / boxplots: use draw color as fill color

Question

I want to fill boxplots according to color that is used to them. For example, for red drawn boxplots, i want to fill it with red. Can you please help me? The code is copied from another topic.

If your code is based on https://tex.stackexchange.com/questions/183778 then please indicate this in your question. In addition, your code has a lot of redundant information. Two addplots are enough to show the problem. — Dr. Manuel Kuehner, Aug 20 '17 at 08:14

You can use

\addplot +[fill] ...

to do that. Note the + before the option list, which means that those settings are appended to the default ones.

A problem with that is that the median line will be hidden, because it has the same color. One way of getting around that easily, is to reduce the opacity of the fill color, with

\addplot +[fill,fill opacity=0.5] ...

You don't actually have to edit each \addplot command though, instead you can add

every axis plot/.append style={fill,fill opacity=0.5}

to the axis options. If you do that, your plot will look like this:
