Two variables in my dataset are important for this question namely : "Country_code" and "Tunnel_status". See example
What I wanted do to now is the following : the availability in BE was 100%, the one in NL was 66% and the one in FR was 33%. I want to filter on the countries with an availability lower then 33% so keep only France. The way how it is visualised is not so important for me, it should just be easy to see and to filter on the country codes with an availability lower then 33%.
Thanks in advance!
