    RadiusFactor Property
    In This Topic
    Multiplicative factor used to increase or decrease the radius of each concentric circle.
    Syntax
    Public Property RadiusFactor As Double
    public double RadiusFactor {get; set;}
    Remarks
    It also represents the distance that separates each concentric circle related to a hierarchical level. When using a radius factor less than 1, the distance that separates the diagram junctions belonging to the (n) hierarchical level and the (n+1) hierarchical level progressively decreases. With a factor greater than 1, the distance between the hierarchical levels increases progressively. The default is 1.
