DxSparkline.BreakOnEmptyPoints Property

Specifies whether the series should break on points with null values.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
[DefaultValue(false)]
[Parameter]
public bool BreakOnEmptyPoints { get; set; }

#Property Value

Type Default Description
Boolean false

true to break the series on null points; otherwise, false.

#Remarks

Set the BreakOnEmptyPoints property to true to display breaks in series where arguments correspond to null values. If you keep this property’s default value, the series excludes null points and no breaks appear on the graph.

The following code snippet adds breaks for null values:

Sparkline - Break on Empty Points

<DxSparkline Data="@DataSource"
             ArgumentFieldName="Month"
             ValueFieldName="VisitorCount"
             BreakOnEmptyPoints="true"
             Height="50px"
             Width="200px">
</DxSparkline>

@code {
    IEnumerable<SparklineDataPoint> DataSource = Enumerable.Empty<SparklineDataPoint>();
    protected override void OnInitialized() {
        DataSource = GenerateData();
    }
}
