PiePrimitiveInfo Class

Represents information used to perform layout of pie charts and used in the databinding of their primitives.

Syntax

Visual Basic
C#

'Declaration
 
<TypeDescriptionProviderAttribute(MS.Internal.ComponentModel.DependencyObjectProvider)>
<NameScopePropertyAttribute("NameScope", System.Windows.NameScope)>
Public Class PiePrimitiveInfo 
   Inherits PrimitiveInfoBase

'Usage
 
Dim instance As PiePrimitiveInfo

[TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
public class PiePrimitiveInfo : PrimitiveInfoBase

Example

The following shows how to use databinding to configure pie slices using the class's Geometry and Interior properties, among others.
