3D Surface Plot Settings
3D Surface Plots are a 3D perspective version of the 2D Surface Plot.
They provide a clearer understanding of the overall “shape” of the surface, but they also introduce occlusion problems; not all data points can be seen due to the display perspective.
The Surface Plot 3D is made up of a series of points where each point has:
- X Position
 - Y Position
 - Z Position (encoded by color)
 
The Surface Plot 3D can support data sets where the X and Y positions can both be regular and irregular in their distribution.
The color scale can be continuous or stepped to show a surface gradient.
Grid lines, a ground plane, and markers for data points can be shown if required.
The 3D surface plot settings pane is displayed after clicking the Options 
  button.

| Setting | Description | 
| 
           Show Axes  | 
        
           Determines whether axes are displayed.  | 
      
| 
           Show Axes Titles  | 
        
           Determines whether axes titles are displayed.  | 
      
| 
           Show X Grid  | 
        
           Determines whether the X Grid lines are displayed and if checked the space in pixels between them.  | 
      
| 
           Preferred X Grid Space  | 
        
           Specifies the X Grid lines spacing. Default is 100.  | 
      
| 
           Show Y Grid  | 
        
           Determines whether the Y Grid lines are displayed and if checked the space in pixels between them.  | 
      
| 
           Preferred Y Grid Space  | 
        
           Specifies the Y Grid lines spacing. Default is 100.  | 
      
| 
           Show Points  | 
        
           Determines whether markers are drawn over surface data points.  | 
      
| 
           Show Ground Plane  | 
        
           Determines whether a ground plane should be drawn below the 3D surface  | 
      
| 
           Rectilinear Grid  | 
        
           Determines whether distinct X and Y values are changed into a rectilinear grid where missing values are filled in with a default of zero (or the ground level).  |
