Add Forecasting to an Existing Visualization

To add data analysis to a line chart, select the drop-down list from the visualization toolbar, and then select Show Forecast.

On the Properties tab for the line chart visualization, you can adjust the number of data points to predict by using the Duration option. You can also specify the degree of confidence for the confidence band by using the Confidence option.

On the Roles tab, you can add measures to the forecast as Underlying factors. The forecasting model evaluates the additional measures to determine whether they contribute to the accuracy of the forecast. If the additional measures do not increase the accuracy of the forecast, then they are not used. If the additional measures do increase the accuracy of the forecast, then the forecast line is adjusted, and the confidence bands are narrowed.

If your forecast includes underlying factors, then you can apply scenario analysis to the forecast. For more information, see Apply Scenario Analysis to a Forecast.
