#### A.5.10.1 Sphere Axes Control

The Axes control () for the sphere plot window has five tabs.

Range tab of the sphere axes control

The Range tab provides manual configuration of the data range of the plot. Making changes to this tab will reset the visible plot range, but not vice versa - zooming and panning in the usual way will not change the settings of this panel. Any values not filled in will be determined from the data.

View tab of the sphere axes control

The View tab can configure how the cube containng the data is viewed in the plot window, though it does not control the content of the cube.

Rotation about Z axis
  Explicitly sets the rotation angle about the Z axis, regardless of its current value, which may have been set by mouse actions.
Rotation from vertical
  Explicitly sets the rotation angle from vertical, regardless of its current value, which may have been set by mouse actions.
Zoom factor
  Sets the magnification of the cube wireframe itself, without affecting the data volume it contains. This cannot be done with the mouse.
X/Y offset of centre
  Controls where on the screen the cube wireframe is centred. This cannot be done with the mouse.

Grid tab of the sphere axes control

The Grid tab configures the appearance of the cube wire frame enclosing the data volume.

Draw wire frame
  Whether the enclosing cube is drawn at all.
Minor Ticks
  If set, minor (unlabelled) tick marks will be drawn between the major (labelled) ones.
X/Y/Z Tick Crowding
  Use the slider to influence how many tick marks are draw on each axis.

Labels tab of the sphere axes control

The Labels tab controls the text labels on the axes. If the Auto checkbox is set, the text will be taken from one of the data coordinates being plotted on that axis. To override those with your own axis labels, unset Auto and type text in to the Label fields.

Font tab of the cube axes control

The Font tab configures the font used for axis annotation. It also affects some other things like the legend.

Text Syntax
  Whether to use plain text or LaTeX rules to make sense of the text value.
Font Size
  Size of the font in points.
Font Style
  Style of the font.
Font Weight
  Whether the font is plain, bold or italic.
