Hello,
Since a few days, I am getting a warning saying 'Specify a UIAxes Handle as first argument' on certain commands associated with the plot functions in appdesigner. These warnings did not appear a couple of months ago, I am just wondering is it due to any update? I am currently using Matlab2020b version.
An example is given below for polar plot. I am getting the same warnings on lines 3,5 and 6.
app.pax = polaraxes(app.Ant_Pat); % Creates polar axes inside the panel
polarplot(app.pax,deg2rad(app.Azimuth_V(600:3000)),pow2db(app.G_ta_v(1800,600:3000)),'g','LineWidth',2);
hold(app.pax,'on'); %getting warning
polarplot(app.pax,deg2rad(app.Azimuth_V),pow2db(app.G_ra_v(1800,:)),'r','LineWidth',2);
legend(app.pax,{'Transmit Antenna','Receive Antenna'},'Location','south'); %getting warning
legend(app.pax,'boxoff') %getting warning
Is there any replacement command in order to avoid these warnings?
Kind Regards
Anum

Its still the axis before and after the polar plot. 'matlab.graphics.axis.PolarAxes'
The warning is hidden after enabling app coding alerts tough.

I think this happens when you use UIFigure or regular Figure that doesn't exist as the Component in the app. What is app.Ant_Pat? See this question, if you specify Panel as the parent of the polarplot, you might not get the warning.

app.Ant_Pat was actually the panel as suggested in the post...
