If they hold that stance, the graph should not use ‘Europe’ when they essentially mean ‘EU member nations’, especially if they omit the UK for the reasons you state as the UK is a part of Europe.
In this case it is the graph makers laziness to not find extra stats on the UK. On the other part I believe the UK has the choice to join again, especially on side project as Eurostat. If a European country doesn’t want to join on European initiatives then I’m bit sure if we should treat them specially. The choice is theirs and it was clearly made.
