So Z axis is coming out of the board or going into the board. Then we have the following three orbitals. Now, if we take these guys and put them together, we get the overall p orbital and it's given by the following picture, which kind of looks like a flower, a three dimensional flower. Now we have the X orbital. So this guy here, we have the y orbital. So this guy here and we have this z orbital, the PV orbital which is coming out of the board.
