How can I plot the antenna array pattern/ the 3D pattern plot in MATLAB App Developer without plotting the figures in a new window?

I am trying to plot some figures in MATLAB App Designer such as the antenna pattern (rectangular and polar), the 3D array pattern, the array structure, etc. I want to plot the figures in the app, without opening them in a new window.

I am using functions such as:

• pattern(app.ArrayURA,app.f,-180:180,-90:90,'PropagationSpeed',app.c,'Type','powerdb','CoordinateSystem','polar','Weights',app.w);
• viewArray(app.ArrayURA,'ShowNormals',true,'ShowIndex','All');
• plotSpectrum(app.estimator, 'NormalizeResponse', true);

How can I do so? I know that it is possible to use the UIAxes function, but how can you use it for a 3D plot or for the antenna array plot?

You can add the following as a workaround (See app attached for an example):

            h = gca;
            app.UIAxes.XLabel = h.XLabel;
            app.UIAxes.YLabel = h.YLabel;
            app.UIAxes.Title = h.Title;

            for ii = length(h.Children):-1:1
            h.Children(ii).Parent = app.UIAxes;
            end
            
            close(gcf)

Hi Kevin, thank you for your answer. I just want to ask you if it is also possible to plot the array structure and/or the 3D plot using this method.

For instance, how can I plot the array structure using the method you mentioned above? viewArray(app.ArrayURA,'ShowNormals',true,'ShowIndex','All');

Or, how can I show the 3D plot?

pattern(ura,fc,-180:180,-90:90,'PropagationSpeed',c,'Type','powerdb',...

'CoordinateSystem','rectangular','Weights',w);

[Kevin Holly]

Yes it is possible. See updated app attached. You can uncomment the line 28 to see the array structure.

Yea it works, thank you so much for your help!

I still have some issues with the polar plot. Is there a way to use the polar axes instead of the UIAxes?

I want to plot the following function:

pattern(array,fc,-180:180,0,'PropagationSpeed',c,'Type','powerdb',...

'CoordinateSystem','polar');

For instance, can I use: "pax = polaraxes(app.parent)"?
