Gauge Class

Contains measures that provide data for a gauge in the GaugeDashboardItem.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v23.1.Core.dll

NuGet Packages: DevExpress.Dashboard.Core, DevExpress.Win.Dashboard.Design


public class Gauge :


Gauges displayed within the GaugeDashboardItem show the actual and target value of a particular parameter, as well as the difference between them. Data used to calculate the actual and target values is provided by a pair of measures - one Measure for each value.

The Gauge objects stored in the GaugeDashboardItem.Gauges collection specify these measures via the KpiElement.ActualValue and KpiElement.TargetValue properties.

The GaugeDashboardItem creates one gauge for each Gauge object in the GaugeDashboardItem.Gauges collection. If the SeriesDashboardItem.SeriesDimensions collection is not empty, multiple gauges are created for each Gauge object - one gauge for each dimension value. To learn more, see GaugeDashboardItem.Gauges.


The following example demonstrates how to bind a Gauge dashboard item to data in code.

            Gauge gauge = new Gauge();
            gauge.ActualValue = new Measure("Extended Price", SummaryType.Sum);

            gauges.SeriesDimensions.Add(new Dimension("Sales Person"));

            return gauges;
        private void Form1_Load(object sender, EventArgs e) {

            dashboardViewer1.Dashboard = new Dashboard();

            DashboardObjectDataSource dataSource = new DashboardObjectDataSource();
            dashboardViewer1.AsyncDataLoading+=(s,ev) => {
                ev.Data = (new nwindDataSetTableAdapters.SalesPersonTableAdapter()).GetData();

            GaugeDashboardItem gauges = CreateGauges(dataSource);
