That's a stupid chart. The "100%" implies that those countries are "done", while the petition needs at least 1.000.000 participants (regardless of their country) and it's missing over 700.000 to reach the goal.
But it also needs a minimum of countries (I think seven) to go over 100 % and only the votes of those countries which actually go over 100 % are counted.
"To be successful, a European citizens' initiative has to reach one million statements of support as well as minimum thresholds in at least 7 countries."
Sounds to me like all votes count, but only if it goes over 1.000.000. And that is the big hurdle here, if you multiply the current votes by 4 to get over a million you automatically have seven countries over the threshold.
