The problem with the lacking data is a crux many fields that are occupied with lbgta issues have unfortunately…(But not be mean, but rejecting certain data, because there can/probably are interests of sponsors involved comes dangerously close to cherry picking, worser in cases in which data is that rare.)
I also just want to point put that the data on the map, pretty much is the data of the survey I linked you the press release first.
I don’t know if you read their Q&A about their methodology and their technical report, maybe it answers some of your questions:

http://fra.europa.eu/sites/default/files/eu-lgbt-survey-technical-report_en.pdf Edit: Okay, you really should read this one, it gives you the absolute numbers and the whole data collecting process, etc. I think it should answer most of your questions about the survey.
Looking at the answers per subgroup at least indicates that trasgender induviduals have to suffer more violence. I certainly would be also happier if I could find more information about the situation in Europe, it would be much more interesting if it would also show the differnces between the differing areas inside the countries: Is it worse on the countryside or in urban areas? Are certain states more prone to certain ways of discrimination, etc.
But as it is we have to work with what we have. And about people saying that it’s pretty bad in a certain country, there are various reasons for that, one being a higher awareness or with what/where the comparision is: Do people compare it to the ideal, which all countries seem to be still far away from or with countries with better circumstances? I think that makes a difference, comparing to something that may be not that far away in the future or some ideal we are still very far away.
Also the number of people that have outed themselve makes probably a difference. Being openly out or being closeted makes a differnce in the ways discrimination works against one.
Still I wouldn’t say that we already as far to say that lbgta people are really largely accepted, tolerated yes, but there still are much things wrong in the perception of lbgta people, when there are still not so few people that need to be told that saying “homosexuals are sick in the head” is a pretty gross (and wrong) thing to say or are against simple things like same-gender marriages (what comes with tax breaks that many couples probably could need) and people out of the lbgta spectrum adopting children.
It’s a kind of tolerance that is build on: “Yes I know I shouldn’t discriminate or attack those people, but I still don’t like/understand it” That’s different from acceptance. And yes much of it comes from lacking education and/or thrive to educate oneself.
