The blue bars show the number of comments for each month; the light blue bars show the expected number of comments calculated by ARIMA using the previous trends, and the red bars are the number of comments relating to COVID-19. The number above light blue bars is the ratio (displayed as a percentage) between the actual number of comments and the expected number of comments, while the numbers above red bars are the ratio (also as percentages) between comments related to COVID-19 and the actual number of comments.
