Dear community,

I have a script that produces multiple figures and I would like to save them automatically to a named folder. I have looked to similar examples at this forum but I still cannot figure out how to create multiple handles. The result is that, although the figures are plotted and seem to be saved in the format I have specified (.bmp), only the lastly created figure is saved in the specified folder.

######################################################################

The code I am using is the following: (this part of the code rests inside a for loop, with n being the counter)

        figure(n) 
        set(gcf)
        set(gca)
        plot((5:5:300),mean(A,1)); % we take an average plot of
                                %the 300ms after all the 40 stimulations of the stimulated
                                %electrode.
        title(['File: ' filename ' Stim electr: ' num2str(StimElectr(n))]);
        xlabel('Latency [ms]'); ylabel('Count'); grid on
        fpath='G:\test'
        saveas(figure(n),fullfile(fpath,'PSTHPlots'),'bmp')

Any help appreciated! Thank you, Stella

Hi @Stelina I am working on a project that requires me to save multipl figure into bmp format to a named path. Really appreciate your advise if you could share with me how you do it. I tried following what u did by doing figure(n) but it keep giving me error.

The <Answer> I gave below does work for the specific case; it's not possible to know where you went wrong without your code and error.

That probably would be more suitable as a new Question rather than follow-up here; one could hazard a guess you've used some other variable than n in a loop or the idea outlined needs to be tailored to your specific code rather than copied verbatim.

saveas(figure(n),fullfile(fpath,'PSTHPlots'),'bmp')

They're all being saved in the location requested but you're not updating the file name so the end result is you're overwriting N-1 previous with the Nth.

You need to update the filename to a unique name for each; perhaps using some variant of the name you've created for the title above.
