Calendar maps: we show how the total daily number (blue) and amount (yellow) of transactions change between 2016 (first and third column) and 2017 (second and fourth column). We can see that there is an increment, both in number of transactions and total amount, in the last days of each month (likely due to the salaries payments) and in particular in June and December (likely because of bonus salaries and taxes)
