LabelArea Constructor(Boolean)

Creates a new label area.

Syntax

Visual Basic
C#

'Declaration
 
Public Function New( _
   ByVal overlay As Boolean _
)

'Usage
 
Dim overlay As Boolean
 
Dim instance As New LabelArea(overlay)

public LabelArea( 
   bool overlay
)

Parameters

overlay: A boolean value that specifies whether the label text overlaps the plot area

Remarks

The overlay can only be set in the LableArea class constructor. The Overlay property is read-only. The default value is false.

When the Overlay property is true, the height of the plot area is adjusted when the TextDirection or TextRotationAngle property in the LabelArea class is changed.

When the Overlay property in the LabelArea class is false, the height of the PlotArea is not adjusted. If there is not enough space for the chart title, the title is painted over the plot area.

Example

This example specifies whether to paint the chart title over the plot area.
