OffsetUnit

Gets or sets the value that indicates the to calculate the range offset either in logical pixel or factor.

public SizeUnit OffsetUnit { get; set; }

Property Value

Type	Description
SizeUnit	One of the SizeUnit enumeration that specifies how the RangeOffset value is considered. The default mode is Pixel.

Examples

<gauge:SfRadialGauge>
    <gauge:SfRadialGauge.Axes>
        <gauge:RadialAxis>
            <gauge:RadialAxis.Ranges>
                <gauge:GaugeRange StartValue="50" EndValue="100" RangeOffset="10" OffsetUnit="Factor" />
            </gauge:RadialAxis.Ranges>
        </gauge:RadialAxis>
    </gauge:SfRadialGauge.Axes>

RangeOffset

Gets or sets the value that specifies the range position. You can specify value either in logical pixel or radius factor using the OffsetUnit property.

Declaration

public double RangeOffset { get; set; }

Property Value

Type	Description
System.Double	It defines offset of the range either in pixel or factor. The default value is double.NaN.

Examples

If WidthUnit is Factor, value will be given from 0 to 1. Here range placing position is calculated by RangeOffset * axis radius value. Example: RangeOffset value is 0.2 and axis radius is 100, range is moving 20(0.2 * 100) logical pixels from axis outer radius. If WidthUnit is Pixel, the given value distance range moves from the outer radius axis. When you specify RangeOffset is negative, the range will be positioned outside the axis.
