Good evening everybody,

I need to make a graph where I have actual data from sales and would like to have an additional curve with predicted sales for the future. I know then I can do this with the forecast funktion or the formula from the trendline but those to are linear function. Whereas I can already see that the actual sales already have an concave curve.

Is there any way I can predict the sales better ?

Thank you very much and best regards

Daniel
