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.
