Why does legend goes to the back of the axes box in multiplots if you click it or move it with the mouse?

Why does legend goes to the back of the axes box in multiplots if you click it or move it with the mouse? This happens specially in subplots or tiled plots (multiplots). I try to move the legend with the mouse somewhere else and immediate is behind the axes box completely concealed and I can not make it visible any more. Only if is on the side of the axes boxes within the gray zone but not inside the axes box where is desired to be.

Are you using multiplot from the File Exchange? What version/environment is this in?

I tried the following in R2019b and I can drag the legend around without any stacking issues.

% using subplots
x = 1:10;
subplot(2,1,1)
plot(x)
subplot(2,1,2)
plot(x)
legend('blasdf')

% using multiplot instead
x = 1:10;
multiplot({x,x},{x,x});
legend('blasdf')

A minimal working example would be helpful.

Thank you, I am attaching this example and image to explain what is happenig. First, if I try to move the legend with the mouse, the first tile gets all distorted and the legend is concealed behind the axes box and there is no way I can bring it back on top of the axes box. I am using Matlab R2021a. Thank you

[nraw,sraw,navg,savg] = Spectra(V.*0.3048,[],Samp_Freq,'dim',10);
loglog(nraw,sraw,'-.g','LineWidth',1);
grid on
ax = gca;
ax.FontSize = 17;
xlabel('${\rm{n }}\,(Hz)$', 'Interpreter', 'Latex');
ylabel('${S_n}$', 'Interpreter', 'Latex');
leg=legend('Spectra of velocity', '', '', '');
leg.Interpreter='latex';
leg.FontSize = 7;
title(['Probe ',num2str(i_probe)])

We can't reproduce the problem without having a minimal working example (e.g. something you provide us that we can run on our end). The code you provided is a decent start but we also need the functions and variable values you're using.

However, I think this may be a problem with how you're creating legends. In your examples, the legends are created without using handles so the legend is assigned to current object which may not correspond to the intended axes.

Instead, use the DisplayName property to assign legend strings to objects and specify axis handles in the legend function.

% Assuming loglog produces 1 handle output, 
loglog(nraw,sraw,'-.g','LineWidth',1, 'DisplayName', 'Spectra of Velocity');
grid on
ax = gca;
ax.FontSize = 17;
xlabel('${\rm{n }}\,(Hz)$', 'Interpreter', 'Latex');
ylabel('${S_n}$', 'Interpreter', 'Latex');
leg=legend(ax);  % specify axis handle
leg.Interpreter='latex';
leg.FontSize = 7;
title(ax, ['Probe ',num2str(i_probe)])   % use axis handle

% If loglog outputs a vector of 4 handles, 
h = loglog(nraw,sraw,'-.g','LineWidth',1);   % store output handle
grid on 
ax = gca;
ax.FontSize = 17;
xlabel('${\rm{n }}\,(Hz)$', 'Interpreter', 'Latex');
ylabel('${S_n}$', 'Interpreter', 'Latex');
leg=legend(h, 'Spectra of Velocity', '' '' '');  % specify axis handle and strings
leg.Interpreter='latex';
leg.FontSize = 7;
title(ax, ['Probe ',num2str(i_probe)])   % use axis handle

Thank you very much for your explanation. It helps very much how to deal these kind of problems.
