### phase

When phase is yes (the default), the orbital is represented with two colors, to distinguish places where the wave function is positive and negative. When phase is no, the whole orbital is represented with just one color.

    Example: <orbital ... phase="yes"/> (default)
    Allowed values: yes, no (optional)

### frame

When frame is yes (the default), a cubic frame is shown around the orbital, with a edge length equal to twice the sampling radius. When frame is no, no frame is shown.

    Example: <orbital ... frame="yes"/> (default)
    Allowed values: yes, no (optional)

### octants

Each orbital is divided in 8 octants, that can be made visible or not, according to a sequence of 8 bits. The 8 octants are ordered from -x-y-z to +x+y+z, where x moves faster and z moves slower, so the first 4 bits (counting from the left) are for the 4 octants with -z coordinate (below) and among these the first 2 bits are for the 2 octants with -y coordinate (below). To set which octants should be shown or hidden, set the corresponding bits to 1 or 0. By default all octants are shown.

    Example: <orbital ... octants="11111111"/> (default)
    Allowed values: all 8 bit sequences (optional)

### 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 unit, axes are shown with a unit length. When axes is set to bohr, axes are shown with the length of Bohr first radius. When axes is set to none, no axes are shown (the default). The options bohr and unit are useful only for small orbitals, otherwise the axes are barely visible.

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.

    Example: <orbital ... axes="none"/> (default)
    Allowed values: radius, bohr, unit, none (optional)
