line graph - show % change above line

[ajm]

I am graphing some government Producer Price Indices, based on the index published for Dec each year, relevant to our products to get an idea of price movement over time. Using a line graph with markers, is there any way to get the % change in yearly index value as a line label between the markers? so, if Dec 20 was 100, Dec 21 was 107, Dec 22 was 111, the line from Dec 20 to Dec 21 would be labelled 7%, from Dec 21 to Dec 22 would be 3.7% and so on.

is it possible?

HI
I think it could be enough to create a series with the differences (in percentage) between one data point and another and then indicate these as labels.

Thanks Mario. not sure how that would work given the percentage changes are not linear
