savefig in loop leads to an empty figure

Hi All,

I'm trying to use savefig in a loop to save some polarhistograms as .fig files and for some reason it saves it properly but when I open the .fig files, it is empty. Any help would be much appreciated. Interestingly, using file--> saveas in the figure window doesn't work either.

for ii = 1:S(1)
    for jj = 1:S(2)
        tmp = bandphase(ii,:);
        C{ii,jj} = tmp(Bandphase_logical(jj,:));

          phases_nonan{ii,jj} = ~isnan(C{ii,jj});
          phases{ii,jj} = C{ii,jj}(phases_nonan{ii,jj});

          if all(isempty(phases{ii,jj}))
          continue

          else
          polarhistograms{ii,jj} = polarhistogram(phases{ii,jj},19);
          savefig(gcf,sprintf('NS6_001_NS3_001_recalled_cluster_%d_band_%d_phaselock.fig',ii,jj));
          [pval{ii,jj}, z{ii,jj}] = circ_rtest(phases{ii,jj});
          [mu{ii,jj}, ul{ii,jj}, ll{ii,jj}] = circ_mean(phases{ii,jj}');
          end
      end
  end

Thanks!

Hi,

Thank you! I've attached a link to the file.

Please let me know if I can provide anything else. I really appreciate the quick response!

The difference between max and min bin edges should be less then 2*pi. Try

polarhistograms{ii,jj} = polarhistogram(abs(phases{ii,jj}),19);

The above might not be what you seeking. But accordingly, I think you need to change your phases values.
