Save training progress plots using OutputFcn

Hi,
I'm trying to save the training progress plots using the OutputFcn training option as written in a previous question:
I'm using Matlab v.2018b and that solution doesn't work, this is the code that I'm using in a live script:
options = trainingOptions('sgdm',...
'InitialLearnRate',0.003,...
'Plots','training-progress', ...
'ValidationData',garVal,...
'ValidationFrequency',40,...
'MaxEpochs',1,...
'LearnRateSchedule', 'piecewise',...
'LearnRateDropPeriod',3,...
'Shuffle','every-epoch',...
'ValidationPatience',5,...
'OutputFcn',@(info)SaveTrainingPlot(info),...
'Verbose',true);
% ... Training code ...
% At the end of the script:
function stop = SaveTrainingPlot(info)
stop = false;
if info.State == "done"
currentfig = findall(groot,'Type','Figure');
savefig(currentfig,'prova.png')
end
end
At the end of the training this error appears:
Functionality not supported with figures created with the uifigure function. For more information, see Graphics Support in App Designer.
The problem seems to be the function savefig (and also saveas has the same problem)... and, if I use gcf instead of groot inside savefig, a blanck picture is saved.
How can I solve the problem? Is there an other way to save the training progress plots?
Thanks!

“savefig” accepts ‘.fig’ file extension only. It does not accepts other file extensions. For more information see the “input Arguments” section in the below MATLAB documentation.
Whereas “saveas” function accepts ‘.png’,’.fig’ and many other file extensions. For more information see the “input Arguments” section in the below MATLAB documentation.
Hope this helps.

Hi, can I use the OutputFcn to add any function I created (in my case : a function that processes the image datastore in a specific way)? Thank you!
