Public Property Calculation As MeasureCalculation| Type | Default | Description |
|---|---|---|
| MeasureCalculation | null |
A MeasureCalculation descendant that specifies a calculation applied to values of the current measure. |
To apply a calculation to values of the required measure, perform the following steps.
The code snippet adds a new measure to the Pivot dashboard item and specifies a window calculation to compute the difference between measure values across a window. The calculation is performed along columns of the Pivot dashboard item.
using DevExpress.DashboardCommon;
using DevExpress.DashboardWin;
// ...
PivotDashboardItem pivotItem = dashboardViewer1.Dashboard.Items[pivotItemName] as PivotDashboardItem;
if (pivotItem != null)
{
Measure extendedPrice = new Measure("Extended Price")
{
Name = "Diff",
ShowGrandTotals = false
};
PivotWindowDefinition pivotWindowDefinition = new PivotWindowDefinition();
pivotWindowDefinition.DefinitionMode = PivotWindowDefinitionMode.Columns;
extendedPrice.WindowDefinition = pivotWindowDefinition;
extendedPrice.Calculation = new DifferenceCalculation() { DifferenceType = DifferenceType.Absolute };
pivotItem.Values.Add(extendedPrice);
}
