You can see the top 10 sales rankings for each year.
Ranking of number of sales. Since it is not a ranking of sales amount, free works and low-priced works may be ranked high.
Rankings are arranged in order of 1st, 2nd, 3rd, etc. from the left.
Even if the number of sales is the same and the ranking is the same, the 10th place is displayed, so there are years when more than 10 works are displayed.
In addition, in the ranking, only works that are currently on sale are displayed, and works that have already finished selling are not displayed.
