Plotting a function from the Communication toolbox in App designer

Hi Everyone,

I am trying to plot a rician impulse and frequency response in App designer and the simulated object image is not staying on the screen. Can someone assist please, this is the code below:

x= (app.ExcessDelayField.Value);
y =(app.RelativePowerdBmEditField.Value);
xconverted=str2double(strsplit(x,','));
yconverted=str2double(strsplit(y,','));
if (not((length(xconverted)==length(yconverted))))
fig = uifigure;
uialert(fig,'Error! Both parameters must have the same amount of values!','Re-enter parameters!'); 
else
    
%  stem(app.Plot1,xconverted,yconverted);
% app.Plot1.YDir = 'reverse';
% xlabel(app.Plot1,'Excess tap delay');
% ylabel (app.Plot1,'Relative power (dB)');
% title(app.Plot1,'Power Delay Profile');

Carrierfrequency_Hz =app.CarrierFrequencyMHzEditField.Value*1e6;
Mobilespeed_ms=(app.MobilespeedkmhrEditField.Value*1000)/3600;
fD= (Carrierfrequency_Hz )*(Mobilespeed_ms)/(3e8); %dopplershift= Mobile_speed * Carrier frequency /speed of light
 samplerate=app.SamplerateMHzEditField.Value*1e6;
 pathdelays=xconverted*1e-9;
% release(rayChan);
ricianChan = comm.RicianChannel('SampleRate',samplerate, ...
    'PathDelays',pathdelays, ...
    'AveragePathGains',yconverted, ...
    'KFactor',10, ...
    'MaximumDopplerShift',fD, ...
    'Visualization','Impulse response');

x1 = randi([0 1],1000,1);
y1=ricianChan(x1);

The ricianChan function doesnot support passing axes or uiaxes as input.

As workaround you can use the data from ricianChan and plot accordingly by targeting the axes in the app designer.
