Overlay Property (LegendArea)

Gets or sets whether the legend area overlaps the plot area.

Syntax

Visual Basic
C#

'Declaration
 
Public Property Overlay As Boolean

'Usage
 
Dim instance As LegendArea
Dim value As Boolean
 
instance.Overlay = value
 
value = instance.Overlay

public bool Overlay {get; set;}

Remarks

If the Overlay property is false, then the height or width of the plot area is adjusted when the LegendArea.Vertical property or LegendArea font size is changed. If the Overlay property is true, the height of the plot area is not adjusted. If the legend area does not have enough space, it is painted over the plot area.

Example

This example sets the Overlay property.
