Ran in:
Hi all,
In GUI (figure), you know that I can keep left mouse and move legend.
figure(1);
p = uipanel('Position',[.1 .1 .8 .8]);
hSub = subplot(1,1,1, 'Parent', p);
t=0:.01:7;
plot(t,sin(t));
legend('sint t');
But in app designer, I can't.
Do anyone know why. Please tell to me how to fix.
Thank you

I have no problems dragging the legend in App Designer. If you upload your app file and provide clear, simple instructions on how to recreate the problem, we could dig deeper.

The legend isn't draggable in your release (R2019b) but it is draggable starting in R2021a.

Hi @galaxy, just create a handle for your legend. See code attached made on R2021b (if you are working on a different release of Matlab, you have to open App Designer and save the file before run it).
% Option 1: create a handle to the legend (declare it as property of your app previously)
app.h = legend(app.UIAxes, 'sint t');
% Option 2: search it when you need it
h = findall(app.UIFigure, 'Type', 'Legend')
