The stack datasets zone is where the [normalised historical data](dataset:historical_ts_data_normalised) and the [ data to forecast ](dataset:to_forecast_data) are stacked in order to simplify the next preparation steps. 

The [prepare recipe](recipe:compute_to_forecast_data_no_driver) is used simply to delete the drivers columns in order to facilitate flow automation until the regression model zone.
