How do I add forecast values to a time series?

You can add forecast values to a raw time series in the series list, or after having applied some calculations to it.

Add a forecast in the beginning of the document

To add a forecast to the raw time series, before any calculations are made, click on "Series list" in the analysis tree. Open the tab called "Forecasts" and click "Edit" next to the series you'd like to add a forecast to.

Please note that these forecasts will be added on the original frequency of the time series, even if the document uses another frequency.
