LabelRotationAngle Property (PolarAngleAxis)
Example 


Gets or sets the rotation angle for the label
Syntax
'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.
