Create a Forecast Chart in Excel 2016

If you have time based on the historical data it can be used to create a forecast. When a forecast is created, a new worksheet is created with a table of historical and projected values and a graph showing this. A forecast can help predict things like future sales, inventory requirements, or consumer trends

In a spreadsheet, enter two sets of data correspond to each other:

A date or time series with the inputs to the timeline

A series with the corresponding values

These values can be predicted for future dates.
