Need help with antenna beam patterns

I need to plot the azimuth antenna beam pattern of the AUT in a rectangular plot given the data (example below)

DATA: Azimuth (deg), Elevation (deg), Power (dBm)

7.317073,8.048780,-38.920000

10.243902,8.048780,-36.600000

13.170732,8.048780,-33.740000

As per my understanding, you want to plot the azimuth antenna beam pattern of the AUT in a rectangular plot.

Here is an example to Visualize 2-D Radiation Patterns of Helix Directivity:

%Calculate the directivity magnitude, azimuth, and elevation angles from a helix's radiation pattern at 2 GHz.
h = helix;
[D,az,el] = pattern(h,2e9);

%Extract theta and phi angles of the directivity magnitude.
phi = az';
theta = (90-el);
MagE = D';

%Plot 2-D phi slice of the antenna in rectangular coordinates.
figure
patternCustom(MagE, theta, phi, CoordinateSystem="rectangular",...
    Slice="phi", SliceValue=0);

Please refer to the document for more information on how to plot radiation pattern using spherical coordinate system (phi and theta angles)
