| Delta |
Gauges allow you to display the difference between the actual and target values of a particular parameter. This difference is called delta.
Delta is shown with a delta indicator (indicating whether the actual value is less than or greater than the target value) and delta values (representing this difference as an absolute value or a variation).
To customize settings that relate to the calculation and display
of deltas, use the options buttons (the 
icon) displayed next to the data item container in the Gauges
section of the DATA ITEMS pane.
These buttons invoke the Gauge Options dialog.
Use it to define the condition for displaying delta indication, specify which delta values should be displayed, and introduce the comparison tolerance.
You can specify which values should be displayed within gauges. Use the Value type combo box in the Gauge Options window to select the value that will be displayed as the delta value.
| Value Type | Result |
|---|---|
| Actual Value |  |
| Absolute Variation |  |
| Percentage Variation |  |
| Percentage of Target |  |
You can specify the condition for displaying delta indication. To do this, use the Result indication combo box in the Gauge Options window.
| Condition | Result |
|---|---|
| Greater is Good | The 'good' indication is displayed if the actual
value exceeds the target value; if the target value
exceeds the actual value, the 'bad' indication is
displayed. |
| Less is Good | The 'bad' indication is displayed if the actual
value exceeds the target value; if the target value
exceeds the actual value, the 'good' indication is
displayed. |
| No Indication | Indication is not displayed. |
| Warning if Greater | A warning is displayed if the actual value exceeds
the target value; otherwise, no indication is displayed. |
| Warning if Less | A warning is displayed if the target value exceeds
the actual value; otherwise, no indication is displayed. |
The comparison tolerance allows you to create more advanced conditions for displaying delta indication. For instance, you can specify that a specific indication should be displayed when the actual value exceeds the target value by 10% or by $2K.
Use the Threshold type combo box to select whether you wish to specify the comparison tolerance in percentage values or in absolute values. Then use the Threshold value box to specify the comparison tolerance.
