Omnidirectional Antennas
The azimuth plane pattern is formed by slicing through the 3D pattern in the horizontal plane, the x-y plane in this case.
The elevation plane pattern is formed by slicing the 3D pattern through an orthogonal plane (either the x-z plane or the y-z plane).

Directional Antennas
Directional antennas are radiating their energy out in a particular direction.
The azimuth and elevation plane patterns are derived by simply slicing through the 3D radiation pattern. In this case, the azimuth plane pattern is obtained by slicing through the x-z plane, and the elevation plane pattern is formed by slicing through the y-z plane.
