### A.4.11 Cube Plot Window

Cube Plot Window

The Cube Plot () plots 3-dimensional Cartesian positions in a 3-d space.

The positional coordinates are X, Y and Z. To control the direction and linear/logarithmic scaling of the axes, see the Coords tab of the Axes control.

The cube plot offers the following plot controls:

- Position Layer Control, with these form options:
  - Mark
  - Size
  - SizeXY
  - Vector
  - Error Bars
  - Polygon
  - Label
  - Line3d
  - Contour
- Pair Layer Control, with the following plot controls:
  - Link2
  - Mark2
- Quad Layer Control, with the following plot controls:
  - Poly4
  - Mark4
- SphereGrid Layer Control

As well as the standard actions, this window additionally provides the following toolbar button:

- Measure Distance

and Subsets menu item:

- Algebraic Subset From Visible

Note that use of the Auto, Density and Weighted shading modes can be confusing in 3 dimensions with multiple datasets. This is because pixels based on density along a line of sight are not located at any point on that line, so shaded pixels can't appear at the "right" place in the 3-d space. The same applies to a lesser extent with contours. They work fine with a single dataset though.

See the Window Overview for features common to all plotting windows. The following subsections describe navigation and axis configuration.

- A.4.11.1 Cube Navigation
- A.4.11.2 Cube Axes Control
