Definition

Namespace:
System.Web.UI.DataVisualization.Charting
Assembly:
System.Web.DataVisualization.dll

Gets or sets the Z coordinate of a 3D point.

public:
 property float Z { float get(); void set(float value); };
[System.ComponentModel.Bindable(true)]
public float Z { get; set; }
[<System.ComponentModel.Bindable(true)>]
member this.Z : single with get, set
Public Property Z As Single

Property Value

Single

The Z coordinate of a 3D point, which is measured as a percentage of the relevant chart area's depth.

Attributes
BindableAttribute

Remarks

This Z property is always expressed as a percentage of the relevant chart area's depth. With 3D charts, Z coordinates are relative, and have a value of 0 for the back wall of the chart area and a value of 100 for the front wall of the chart area.

Note This Z property may be less than zero (located behind a chart area) or greater than 100 (located in front of a chart area).

Any point used in custom 3D drawing - which is accomplished using GDI+ - must be transformed from X, Y and Z (3D) coordinates into X and Y (2D) coordinates using the TransformPoints method. This method takes an array of Point3D objects as its only parameter. By calling the TransformPoints method, the X and Y property values are changed to reflect the 3-dimensional space.

These new X and Y coordinates are then converted to absolute coordinates by using the GetAbsolutePoint method. They are then used for GDI+ method calls.

Relative Z coordinates can be obtained for series by using the GetSeriesDepth and GetSeriesZPosition methods.
