Hello guys,

I would like to have an expert advise on point plotting and if the following is possible in Excel.

I have values from year 1996 to 2021 which forms a curve and I have the end value for year
2030. I want to trace the points between 2021 and 2030 based on the pattern of past values
(i.e. values between 1996 and 2021).

It is possible? Please help me out guys, I am stuck with my thesis.Example.jpg
