By default, the Predictor Results window contains a chart of historical and predicted values in the upper left.
To control the chart view, use these settings:
Periods to forecast— Determines the number of predicted values that are displayed in the chart
Prediction interval—Indicates which prediction interval to calculate and plot
Series—Selects the data series to display in the chart
Method—Selects the method to use for calculating predicted values
View menu—View, Table changes the chart display to a table; View, Chart changes it back; and View, Show Statistics hides and displays the statistics tables to enlarge the chart
Note:
If Include events is selected in the Data Attributes panel of the Predictor wizard, and at least one event is defined, Table View includes an Event column with the name and number of each event defined for the selected series.
Preferences menu—Contains the following options:
Preferences, Chart Preferences displays the Chart Preferences dialog (see Customizing Charts, following).
Preferences, Show All Error Measures shows and hides error measures that are not selected in the Options panel of the Predictor wizard.
Preferences, Show Simulations for Prediction shows and hides a plot of predicted values for each time period (Animating Prediction Simulations).
Preferences, Highlight Seasonality graphically emphasizes seasonal data cycles if present.
Preferences, Highlight Screened Data emphasizes filled-in or adjusted-outlier data if these are present and you selected at least one of the Data Screeningsettings in the Data Attributes panel.
Preferences, Highlight Events emphasizes data defined as events if you have defined at least one event and selected Include events in the Data Attributes panel.
Preferences, Highlight Prediction Interval shows and hides a shaded band that represents the prediction interval selected for the displayed series.
Note:
This feature is available in Crystal Ball 11.1.2.4.400 only. For information on the 11.1.2.4.400 new features and on updating to 11.1.2.4.400, see the Crystal Ball 11.1.2.4.400 Readme and My Oracle Support.
As shown in the chart legend, the green line represents the historical data, the blue lines represent fitted and predicted values, and the orange dotted lines above and below the predicted values represent the upper and lower prediction interval. A gap between the historical and predicted values delineates the past and future values.
Of the classic time-series forecasting methods, only the seasonal methods and multiple linear regression result in curves that approximate repeated data patterns.
