Hello everyone, for starters, you must know, acumulated expression check on the chart propieties doesn't solve my problem.
You have attached an example, I have arrives per month, and I need to show the percentual type of arrive per month, but acumulated by the last 3 months (sheet 1, data table, sheet 2, expected "chart"). Please check de formulas and the coments on the Excel worksheet.
How can I do it on the chart?
Thank you all!!
