Set here how the volume representation of an orbital.
Phase
When 
Phase is switched on (the default), the orbital is
represented with two colors, to distinguish places where the wave
function is positive and negative. When 
Phase is switched off,
the whole orbital is represented with just one color.
Frame
When 
Frame is switched on (the default), a cubic frame
is shown around the orbital, with a edge length equal to twice
the sampling 
Radius defined in the 
Scope page.
When 
Frame is switched off, no frame is shown.
Octants
Often it is useful to show only parts of the orbital.
In GAMGI each orbital is divided in 8 octants, four above
the xy plane, marked as positive, and four below, marked
as negative. The four octants, above and below, are numbered
increasing in a counter-clockwise pattern, as usual in trigonometry.
To set which orbital octants should be represented,
switch on / off each of the eight octant buttons.
By default all octants are shown.
Axes
When 
Axes is set to 
Radius, axes are shown
with the radius length (when 
Frame is disabled) or
the diameter length (when 
Frame is enabled). When
Axes is set to 
Bohr, axes are shown with
the length of Bohr first radius. When 
Axes is set
to 
Unit, axes are shown with a unit length. When
Axes is set to 
None, no axes are shown
(the default). 
When 
Frame is enabled (the default), axes are positioned
along the frame edges, starting from the xyz lower corner. When
Frame is disabled, axes start from the orbital center.
The options 
Bohr and 
Unit are useful only for
small orbitals, otherwise the axes are barely visible.
