I understand that you want to add ticks and numbers to the elevation and azimuth in polar axes. The “patternCustom” function generates a 3D Cartesian plot (axes) and to display ticks and labels, manually set them on the Cartesian axes (X and Z axes) to indicate azimuth and elevation, respectively.
Below is an example code for the same:
% Example Data
azimuth = -180:10:180; % Azimuth angles in degrees
elevation = -90:10:90; % Elevation angles in degrees
[Az, El] = meshgrid(azimuth, elevation);
magnitude = abs(cosd(Az)) .* abs(cosd(El));
% Reshape Data for patternCustom
Az = Az(:);
El = El(:);
magnitude = magnitude(:);
% Plot Using patternCustom()
figure;
patternCustom(magnitude, Az, El);
% Access Current Axes
ax = gca;
ax.Visible = 'on'; % Ensure Axes are visible
Setting Azimuth (θ) ticks and labels on the X-axis using "xticks()" and "xticklabels()".
% Set Azimuth (θ) Ticks and Labels (X-Axis)
xticks(-180:45:180); % Set tick positions
xticklabels(string(-180:45:180)); % Set tick labels
Setting Elevation (φ) ticks and labels on the Z-axis using "zticks()" and "zticklabels()".
% Set Elevation (φ) Ticks and Labels (Z-Axis)
zticks(-90:30:90); % Set tick positions
zticklabels(string(-90:30:90)); % Set tick labels
Adjusting the viewing angle using "view()" to make the data more interpretable.
% Set Axis Labels
xlabel('Azimuth (°)');
ylabel('Magnitude');
zlabel('Elevation (°)');
view(135, 30);
grid on; % Show grid for clarity
% Ensure the plot is refreshed
drawnow;
This approach provides a visual representation of azimuth and elevation angles like what you might expect from a polar plot. If true polar plotting is required, consider using MATLAB's polar plotting functions, such as “polarplot” or “polaraxes”, which are specifically designed for polar coordinates.
