MATLAB: MATLAB App Designer hold on/off throwing warnings

Question

I'm beginner and trying to use polarplot and hold on/off in MATLAB App Designer. Now to use this in app designer, we need to create the polar axes by calling the polaraxes function in the app designer panel container.

I tried this which is working fine without any error:

pax = polaraxes(app.Panel);
polarplot(pax,th,r1,'red')
hold(app.UIFigure.CurrentAxes,'on');          % warning

polarplot(pax,r2,'green')
hold(app.UIFigure.CurrentAxes,'off');         % warning

But due to app coding alerts, I'm getting the warning "Specify a UIAxes handle as first argument" for the hold line. How do I resolve this warning ? Is this the correct way to use hold on/off for the panel container?

Answer 1

I would set the "NextPlot" property of the polar axes to "add".

pax.NextPlot = 'add';
