I am wondering how I could compare the variation in percentage between the same month in two different years.
I have a table element with all 12 months of the year and the electricity consumption of every month. I want to compare the same month of two different years for example:
kWh January 2022: 100, kWh January 2023: 200, variation: +100%
The same thing should be done automatically with every single month in the table element.
How could I do it?
