Change Display Properties Dialog: Value
The Change Display Properties Dialog allows you to change the appearance and values used for a field in a chart or spreadsheet. The Value page allows you to select how to modify the value before it is displayed.
Ä Note: This page is not available for composite chart fields.

Modifying the Value of a Chart Field
Several different value modifications can be applied to a data field before it is displayed in a chart. These value modifications do not change the value of the data field, only the value that is charted.
¨ Sub-value
This option selects other sub-values for the field being displayed. These sub-values are the same as those listed on the Display Fields Dialog.
· Value
This sub-value displays the actual value of the field. This is the same value that is displayed if the field name is selected.
· Change in Value
This sub-value displays the change in the value of the field from the previous bar.
Ä Note: If the previous value is null, the change is considered to be null.
· Percent Change in Value
This sub-value displays the percent change in the value of the field from the previous bar.
Ä Note: If the previous value is zero or null, the percent change is considered to be null.
· Raw Prediction Output
This sub-value displays the value of the neural network without postprocessing. In other words, if this field was predicted using percent change preprocessing, the value being displayed would be the predicted percent change. In addition, any postprocessing applied to predicted signals is removed.
· Error in Prediction Value
This sub-value displays the difference between the predicted value and the desired value.
Ä Note: If the desired value is null, the error will also be null.
· Error in Raw Prediction Output
This sub-value displays the difference between the raw prediction output and the desired value without postprocessing. In other words, if this field was predicted using percent change preprocessing, the value being displayed would be the difference between the predicted percent change and the actual percent change.
Ä Note: If the desired value is null, the error will also be null.
þ Use Absolute Value
This option displays the absolute value of the current value. This is useful for displaying the relative volatility of change values without showing the direction of the change.
¨ Bars to Offset Value for Change/Prediction
For Change and Percent Change displays, this setting controls the number of bars over which to calculate the change in value.
: Example: To display the change in value between today’s value and yesterday’s value for a data series with daily data, this value should be set to 1.
¨ Bars to Shift Display of this Field Forward
Advances the value forward before displaying it. This is useful for displaying predicted values on the day they are predicted for, rather than on the day with the data they are being predicted from.
Ä Note: The shifting bars of prediction error values cannot be modified.
¨ Bars to Combine to Create a Moving Average
Applies a simple moving average to the data before charting it. This is useful for smoothing out volatile data without having to calculate a separate data field with a moving average.
