Matlab Online Figures Won't Close

I have a Simulink / Matlab program that runs scrips and generates many figures. They are generated in a script and then closed in the same script. When I run it on the computer the figures close. When I run it online however, the figure contents close but there is a blank figure left that will not close at all. I have to exit Matlab Online and open a new session to ever get rid of them.

How do I properly get Matlab figures to close online?

figure(101);
hold on;

plot(BASEQ.Time,BASEQ.LSAngularWorkonArm);
plot(BASEQ.Time,BASEQ.RSAngularWorkonArm);
plot(BASEQ.Time,BASEQ.LEAngularWorkonForearm);
plot(BASEQ.Time,BASEQ.REAngularWorkonForearm);
plot(BASEQ.Time,BASEQ.LWAngularWorkonClub);
plot(BASEQ.Time,BASEQ.RWAngularWorkonClub);

ylabel('Work (J)');
grid 'on';

%Add Legend to Plot
legend('LS Angular Work','RS Angular Work','LE Angular Work','RE Angular Work','LW Angular Work','RW Angular Work');
legend('Location','southeast');

%Add a Title
title('Angular Work on Distal Segment');
subtitle('BASE');

%Save Figure
savefig('BaseData Charts/BASE_Plot - Angular Work');

%Close Figure
close(101);

Can you try using explicit handles for all your graphics calls?

I managed to get it running by adding a 1 second pause after saving. A bit inconvenient as there is probably 150 total charts the program creates so it will add a few minutes to the process.

Would an explicit handle help prevent needing the pause?

Worth a try

hfig1 = figure('Name', 'Figure 1');
% Do stuff, then close it explicitly
close(hFig1);
drawnow; % Force immediate update of screen instead of waiting.
