Visualization of the 3d wave function
of an H₂⁺ state 
The phase is mapped to the hue, while the amplitude determines saturation and transparency. The internuclear distance goes from bottom to top, the radial distance of the electron from front to back and its axial distance to the center of mass from left to right.
(move mouse over figure to get an illustration of the densities and flux densities in cartesian coordinates for the same state)
The figures have been created using ZIBAmira .
