## Data Space Properties

The data space contains the data type(s) displayed within the visualization, plus the axes associated with the data. It is a transparent-walled bounding box by default. When the data space walls are not transparent, some display artifacts may be visible in certain situations. See Rendering Objects at Data Space Depth for more information.

These properties control the visualization of the data space. For each property, the type of control and the values that can be assigned are listed. For a description of how a particular control is used, refer to Property Controls.

Table D-40: Data Space Properties

Table D-40: Data Space Properties
Property | Control Type: Values
--- | ---
Isotropic scaling | Scaling method. Select a method from the list. Choose between these values: Automatic: automatic scaling Isotropic: isotropic scaling Anistropic: anistropic scaling Default = Automatic Note - If this property is set to Automatic, then: 1. If any visualization within the dataspace has its Isotropic scaling property set to True, the dataspace will be automatically set to isotropic, and the Anisotropic 2D/3D scale properties will be desensitized. 2. If none of the visualizations are isotropic, the dataspace will be automatically set to anisotropic, and the appropriate Anisotropic scale property will be sensitized for either 2D or 3D data.
Anistropic 2D scale | Presentation scale factor applied along Y axis
Anistropic 3D scale | Presentation scale factor applied along Z axis
Map projection | Default = No projection (click to edit)
X Minimum | Number: Minimum value for X coordinate of data set.
X Maximum | Number: Maximum value for X coordinate of data set.
Y Minimum | Number: Minimum value for Y coordinate of data set.
Y Maximum | Number: Maximum value for Y coordinate of data set.
Z Minimum | Number: Minimum value for Z coordinate of 3-D data set.
Z Maximum | Number: Maximum value for Z coordinate of 3-D data set.
Automatic X range updates | Boolean: Automatically updates the range of X values. Choose True or False. Default = True
Automatic Y range updates | Boolean: Automatically updates the range of Y values. Choose True or False. Default = True
Automatic Z range updates | Boolean: Automatically updates the range of Z values. Choose True or False. Default = True
X log | Boolean: Determines X axis type. Choose True (logarithmic) or False (linear). Default = False.
Y log | Boolean: Determines Y axis type. Choose True (logarithmic) or False (linear). Default = False.
Z log | Boolean: Determines Z axis type. Choose True (logarithmic) or False (linear). Default = False.
Color | Color: Data space bounding box border color. Border Style must not be No line. Click to choose from the default color palette, or specify RGB values. Default = [`0,0,0]` (black)
Linestyle | Line Style: Data set bounding box border line style. Select a line style from the list. Default = No line
Thickness | Line Thickness: Data set bounding box border line thickness. Select a thickness from the list. Default = 1.
Fill Background | Boolean: Fills data space background with background color. Choose True or False. Default = True
Fill Color | Color: Data space background color. Fill Background must be set to True. Click to choose from the default color palette, or specify RGB values. Default = [`255, 255, 200]` (cream)
Transparency | Number: Transparency of data space background from 0% to 100%. Fill Background must be set to True. Move slider to select a new percentage. Default = `100`

### Rendering Objects at Data Space Depth

The depth buffer is a record of the depth at which each pixel of a graphic primitive is rendered on a graphics device. This is typically used to control the visual positioning of objects in front or behind other objects. (See Controlling the Depth of Objects in a View for more information on depth buffers.)

Data space walls are polygon objects that are transparent by default. In unusual circumstances when the walls are not transparent, and when another object is drawn in the same plane, display artifacts may be visible when the objects are transformed. This results from the normal competition between z-buffer and polygon rasterization operations. To avoid any display artifacts, reposition the object so that it is not in the same plane as the data space wall, or make the wall completely transparent.
