Hightlight Box Plot

[#1]

Hello,

I have a situation with  Chart with Box Plots.

I'm trying to highlight a Box Plot when I select it, and to colour the other charts in grey.

But I don't know how to do. I tried to force Qlickview to display all Box Plots, even if there is a selection filter, but it doesn't work.

You can find an example in the attached document.

Does someone know how fix this problem?

Thank you for your future answers

Regards
