English: 2D array visualizing all real spherical harmonics up to l=10. Spherical harmonics are visualized on polar plots. The magnitude of the spherical harmonic is represented by the saturation of the polar plot at a given polar and azimuthal angle and the phase of the spherical harmonic is represented by the hue at given polar and azimuthal angles.
The factual accuracy of this graphic is disputed. The attribution of m=-1 and m=1 numbers to the real-valued spherical harmonics is incorrect. The depicted harmonics are rather superpositions of +m and -m. Correct naming is possible in terms of x, y and z.
