MeasureCalculation Class

Serves as the base class for classes that are measure calculations allowing you to apply specific computations to Measure values that are related to the currently processed value.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v24.1.Core.dll

NuGet Package: DevExpress.Dashboard.Core

Declaration

public abstract class MeasureCalculation :
    ClonableModelBase<MeasureCalculation>,
    IWindowCalculation

Remarks

To apply a calculation to values of the required measure, perform the following steps.

Example

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);
}
