e plane and h plane pattern in cst for antenna

hello, i dont know what we can understand from e plane and h plane patterns of antenna
for example i attach both e-plane (left picture) and h-plane(right picture) patterns of two different antennas (solid line is e-plane pattern of one of them and dash line is e-plane pattern of the other) . can we make a comparison btw their operation just with the help of these patterns?
