A.5.9.1 Cube Axes Control

The Axes control () for the cube plot window has six tabs.

Coords tab of the cube axes control

Coords tab of the cube axes control

The Coords tab controls the axis coordinates. It has the following options:

X/Y/Z Log
If selected, X/Y/Z axis coordinates are logarithmic, otherwise they are linear.
X/Y/Z Flip
If selected, X/Y/Z axis coordinate axes run in the opposite direction to normal.

Range tab of the cube axes control

Range tab of the cube axes control

The Range tab provides manual configuration of the visible 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.

Filling in the Minimum/Maximum fields for one or more axes will constrain the corresponding range of the visible data. The limits corresponding to any of those fields that are left blank will initially be worked out from the data. The Subrange double-sliders restrict the ranges within the (explicit or automatic) min/max ranges. Note you can move both sliders at once by grabbing a position between the two.

The Clear button resets all the fields. The Submit button updates the plot with the current values in this tab, as does making any changes to it.

View tab of the cube axes control

View tab of the cube 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/Z offset of centre
Controls where on the screen the cube wireframe is centred. This cannot be done with the mouse.

Grid tab of the cube axes control

Grid tab of the cube 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 cube axes control

Labels tab of the cube 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

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.
