A.4.11 Cube Plot Window

Cube Plot Window

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

By default the positional coordinates are X, Y and Z, but the Coordinates selector lets you specify them in different ways:

Components:

Coordinates X, Y and Z, giving the Cartesian components of the position.

Vector:

A single coordinate XYZ which must be a 3-element array giving the three Cartesian components of the position. If the array has more than three elements, later ones are ignored.

Polar:

Coordinates Lon, Lat and Radius, giving the spherical polar coordinates of the position.

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

• 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.
