Eurovision - Why some songs got Zero points? Analysis of detailed results. How close it was?

As we all know, according to the current system of voting in the Eurovision Song Contest, juries and televoters of each country make their tops from the least favourite to favourite and their tops 10 receive points (1st place - 12 points, 2nd - 10 points, ... , 10th place - 1 point). At the same time, all the places from 11th to dead last get the same amount of points - zero. So, if some country isn't in top 10 of any voting country, it gets zero points in the relevant category (jury, televoting, overall). Let's look at the zero pointers since Eurovision 2014 and find out how close they were to getting at least one point? Results are actually quite interesting. Enjoy)
