HoleSize Property

Visual Basic
C#

'Declaration
 
Public Property HoleSize As Single

'Usage
 
Dim instance As PiePlotArea
Dim value As Single
 
instance.HoleSize = value
 
value = instance.HoleSize

public float HoleSize {get; set;}

Exception	Description
System.ArgumentOutOfRangeException	value is less than zero or is greater than or equal to one.

Hole size is measured relative to the pie radius (0 = no hole, 1 = full pie radius).

This example sets the HoleSize property.
