How can I set the file name as my title name in a subfolder for numerous plots

2 views (last 30 days)
I am trying to set the title name (that varies depending on the plot) as the file name in a subfolder. I get the error code: Error using sprintf. Function is not defined for 'cell' inputs.
So there is some mistake with my syntax. I have tried different approaches but I don't get it to work. My code is as follows:
figure Timestep=(1:length(d_f_t(:,1)))'; plot(Timestep,W_per_K_serie, '*'); title(['Byggnad', subfolderNames(b)])
saveas(fullfile(folder_path, sprintf('%s.jpg',get(get(gca,'title'),'string'))));
Does anybody have any advice? Thank you in advance

It doesnt't work still unforuntately. My error is now:' Error using saveas. Invalid handle'.
The code looks as follows:
folder_path='XXXXX'; mkdir(folder_path);
tmp = char(get(get(gca,'title'),'string')); saveas(fighandle, fullfile(folder_path, sprintf('%s.jpg', tmp)));
It is noteworthy that my title changes name for every loop I'm performing. However, this should not affect the result? Thank you in advance.

The title 'String' property may be a cell array, string array, or a char vector. You can easily convert this into a char vector:
tmp = char(get(get(gca,'title'),'string'));
saveas(figH, fullfile(folder_path, sprintf('%s.jpg',tmp)));
I would recommend that you avoid gca, gcf, etc., and always obtain and use explicit graphics handles for all graphics objects that you need to refer to.

Yes, I am calling on the function with plot. I got it to work with gca instead of fighandle. However, some parts of the text in the title got misarranged in the jpg file. That I don't understand. Thank you!
