Public Property ViewerRotation As Single

'Usage
 
Dim instance As View

instance.ViewerRotation = value
 
value = instance.ViewerRotation

[DefaultValue()]
[Category("General")]
[Description("The rotation (or tilting) of the camera.")]
public float ViewerRotation {get; set;}

The ViewerRotation specifies the rotation around the axis defined by the chart center point (0, 0, 0) and the camera coordinates defined by the Elevation, Rotation and Distance(not exposed because it is computed dynamically) properties. You may need to modify the ViewerRotation when you want to display horizontal or top to bottom charts. However for such purposes it is recommended to use the PredefinedChartStyle property of the Chart object, because it also changes the chart axis label positioning and others.

The following example modifies the ViewerRotation applied on the chart camera to display a left to right horizontal chart.

Visual Basic

Dim chartView As View = (CType(ChartControl.Charts(0), Chart)).View 
xchartView.Projection = ProjectionType.Perspective
chartView.ViewerRotation = 270

C#

View chartView = ((NChart)NChartControl.Charts[0]).View;
chartView.Projection = ProjectionType.Perspective;
chartView.ViewerRotation = 270;

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
