How to create a 180 degree polar plot in App designer using UI components from the menu

I am trying to create a MATLAB application using MATLAB App Designer for my electroacoustics project.

GOAL:

Use HC-SR04 ultrasonic distance sensor, with Arduino UNO and MATLAB Support Package to create a system for visualizing distances.

HARDWARE:

Arduino UNO, HC-SR04 ultrasonic distance sensor and a servo motor ( SG90 or MG90S ).

SOFTWARE:

Only MATLAB App to communicate using USB port and display sensor data.

PROBLEMS:

I want to use a semicircular plot ( which I found out is called polar plot ). Polar plot enables me to plot distance with respect to the angle of the sensor ( corresponding to the angle of servo motor ). I want to use it in range from 0 to 180 degrees.

• App Designer component library offers only one similiar component which is Axes. This component doesn't allow for enough customization.
• I have managed to use the polar axis using the code bellow

This code does show the plot I need, and I used a slider to try and testout some values on the plot which causes the most irritating problem which is when calling polarplot my polaraxes's properties reset, meaning I lose my setting of ThetaLim to 0 - 180 deg.

The other thing is that creating components using code doesn't show them in APP LAYOUT which means push-pulling values to get them right. Using Panels helps here, but some flexibility in the tool would be greatly appreciated.

Please keep in my mind that I am a beginner and have used MATLAB App Designer successfully for my mechatronics project, but in it I had no need for modding the graphs.

-Thanks in forward

        % Code that executes after component creation
        function startupFcn(app)
            app.PolarCoords = polaraxes(app.Panel);
            app.PolarCoords.ThetaLim = [0 180];
        end

        % Value changing function: Slider
        function SliderValueChanging(app, event)
            changingValue = event.Value;
            polarplot(app.PolarCoords,changingValue);
        end
