Figures – average users rating of banks from 2005 to 2016. Each bank in each year received 13 evaluations: one total + 12 for separate activities. Each user put a rating from 0 to 5. Average rating is the sum of all user ratings divided by the number of them.
Visualization is a heat map formed by overlapping linear graphs for each bank. Enlightenments on the heat map show places where there was a wide gap between banks ratings, dark areas – where they were on par. There is a historical minimum and maximum on every heat map. The darker is the area near them, the closer to them was the overall level of banks that year.
