DxChartSeriesLabel.RadialOffset Property

Specifies the radial offset of pie series labels.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(0)]
[Parameter]
public double RadialOffset { get; set; }

Property Value

Type	Default	Description
Double	0	The radial offset in pixels.

Remarks

The RadialOffset property value radially shifts series labels. A positive value shifts labels away from the chart center, a negative value – towards the center.

Note

The RadialOffset property value applies to DxPieChartSeries labels only.

The following code snippet uses a spin editor to shift series labels radially:

Razor

<label><strong>Radial Offset, px: </strong></label>
<DxSpinEdit @bind-Value="@CurrentRadialOffset" Increment="10" />

<DxPieChart Data="@DataSource"
            Height="350px">
    <DxPieChartSeries ArgumentField="@((StatisticPoint v) => v.Country)"
                      ValueField="@((StatisticPoint v) => v.Population24)"
                      Name="2024">
        <DxChartSeriesLabel Visible="true"
                            RadialOffset="@CurrentRadialOffset"
                            FormatPattern="{argument}: {value}">
            <DxChartSeriesLabelConnector Visible="true" />
        </DxChartSeriesLabel>
    </DxPieChartSeries>
    <DxChartLegend Visible="false" />
    <DxChartTitle Text="Population by European Country, 2024" />
</DxPieChart>
