Inconsistency in the radiation pattern of the dipole antenna

I'm learning Antenna Toolbox and I've encountered this inconsistency.
Let's consider the default antenna dipole.
d=dipole;
pattern(d,70e6)
We'll have, as expected,
As in the guide example,
patternAzimuth(d,70e6,[0 45])
But, if I want only the pattern Azimuth at el=0°, I think I should enter simply this:
patternAzimuth(d,70e6,0)
But I obtain a completely different (and - I think - wrong) pattern. It is also non consistent with the above 3D pattern
I can't understand where is the problem. Could you help me?

The difference you see in the shape of the two patternAzimuth have to do with the magnitude limits of the plot. In the first figure of patternAzimuth at 0 and 45 degrees elevation, the plot has magnitude limit of [-2 3] and in the second plot of patternAzimuth at 0 degrees elevation, the magnitude limit is [2 2.11].
Refer the links below for more information on controlling the patternAzimuth plot properties,
