The period in which the income is calculated depends on the scope of the period you analyze.
If the comparative analysis is annual, then the income is the annual cumulative income. Including the cumulative analysis at the end of this year's reporting period, this year and the same period of last year.
If it is analyzed on a monthly basis, the income is the income of the month. There is a comparison between this month and last month, and there is also a comparison between months of the year.
The chart is quarterly analysis, and the income must be quarterly income. There are comparisons between quarters.
