The Ox_3d_unit_vector command takes no arguments and draws the unit vector in the x-direction on a 3D graphic screen.
| Ox_3d_unit_vector() |
Similarly, the Oy_3d_unit_vector and Oz_3d_unit_vector commands draw the unit vector in the y and z directions, respectively.
These commands have no parameters, but can be decorated with the legend command.
