LabelRotationAngle Property (PolarAngleAxis)

Gets or sets the rotation angle for the label.

Syntax

Visual Basic
C#

'Declaration
 
Public Property LabelRotationAngle As Integer

'Usage
 
Dim instance As PolarAngleAxis
Dim value As Integer
 
instance.LabelRotationAngle = value
 
value = instance.LabelRotationAngle

public int LabelRotationAngle {get; set;}

Remarks

The rotation angle only has an effect if the text direction is horizontal.

Example

This example sets the orientation and angle.
