How can I set "legend" and "text" to an UIAxes? (app designer)

Hello, which functions can I use to include legend and text in my App plot? The version for regular code is this one:

legend('datos','ajuste',"location","best");text(10,0.155,strcat('R²= ',Rcuadrado))

You need to specify the axes within App Designer. Try this:

 %use whatever your UIAxes name is. I assumed it was app.UIAxes
legend(app.UIAxes,'datos','ajuste',"location","best");
text(app.UIAxes,10,0.155,strcat('R²= ',Rcuadrado))

Thank you Cameron, it worked for the legend but no for the text, eventhough it shows no error, R^2 is not visible in plot

            plot(app.UIAxes,tT,Q1,'mo',tT,fit1,'b-');
            app.UIAxes.Title.String='Caudal vs tiempos totales';
            app.UIAxes.XLabel.String='Tiempo (s)';
            app.UIAxes.YLabel.String='Caudal (L/s)';
            legend(app.UIAxes,'Datos','Ajuste',"location","best");
            text(app.UIAxes,10,0.155,strcat('R²= ',Rcuadrado))

The text is placed at the point (10,0.155). The point (10,0.155) is outside the limits of the axes. That's why you don't see the text.

You're right, thanks!
