hi I've got the followed code and I want to get a diferend name for each figure my code does. How can i do it?
AllFigH = allchild(groot);
for iFig = 1:numel(AllFigH)
fig = AllFigH(iFig);
Folder = ('C:\Users\vicen\Desktop\TFG Vicenç\Imagenes\Imagenes Geoscatter\DIA 1')
FileName = ['%03d', '.png'];
saveas(fig, fullfile(Folder, FileName));
end
thank you in advance!!

It looks like you wanted to do,
AllFigH = allchild(groot);
for iFig = 1:numel(AllFigH)
fig = AllFigH(iFig);
Folder = ('C:\Users\vicen\Desktop\TFG Vicenç\Imagenes\Imagenes Geoscatter\DIA 1')
FileName = sprintf('%03d.png', iFig); % <-----
saveas(fig, fullfile(Folder, FileName));
end
I recommend using
AllFigH = findall(groot, 'type','figure')
rather than
AllFigH = allchild(groot);
Update: avoid overwriting filenames
This version searches the folder for png files with a naming structure of ###.png and then determines the maximum number in the file names. The new file numbers will continue with the next value.
Folder = 'C:\Users\vicen\Desktop\TFG Vicenç\Imagenes\Imagenes Geoscatter\DIA 1';
% Get all png filenames in folder.
filedata = dir(fullfile(Folder,'*.png'));
% Determine the max number in the file names ###.png
if isempty(filedata)
lastFileNumber = 0;
else
filenames = {filedata.name};
filenumStr = regexp(filenames,'^(\d+).png$','tokens','once');
filenums = str2double([filenumStr{:}]);
lastFileNumber = max(filenums);
end
% Save figures with new numbers in the file names
AllFigH = findall(groot, 'type','figure');
for iFig = 1:numel(AllFigH)
fig = AllFigH(iFig);
FileName = sprintf('%03d.png', lastFileNumber + iFig); %
saveas(fig, fullfile(Folder, FileName));
end

@vicente Noguer OK, sorry for the misunderstanding. For future reference, it's a good idea to include any functions your code is dependent on so that others can run it (and to avoid any ambiguity about what they might be).

I would call exportgraphics() everytime you're done creating a plot. I'd create it immediately, not sometime later after all plots have been made.

@Adam Danz I said some messages before I generate the figures with geoscatter and I upload the code(I do not know if you meant that) and I have never listened about uicomponents so thats why I was surprised. I got this warning but I could save the images the only problem I have is to save them in the folder I want. With saveas() I did not get any error of uicomponents
