Question

One spss is the interval width the same thing as the bind width? If not how do I edit bin width?

Answer 1

Hello,

You can use the doc histc function to edit the bin width.

Basic code for this is below. Hope you can refer from this.

    %# compute center of bins (used as x-coord for labels)

          bins = ( edges(1:end-1) + edges(2:end) ) / 2;

          %# histc

          [counts,binIdx] = histc(DATA, edges);

          counts(end-1) = sum(counts(end-1:end)); %# combine last two bins

          counts(end) = [];                        %#

   %         %# plot histogram

          bar(edges(1:end-1), counts, 'histc')

                      for c=1:numel(counts)

                          if counts(c)~=0

                              text(bins(c), counts(c)+0.3, num2str(counts(c)), 'FontWeight','bold', 'FontSize',8, ...

                                  'VerticalAlignment','bottom', 'HorizontalAlignment','center');

                          end

                      end

                      set(gca,'ylim',[0 max(counts)+1/10*(max(counts))]); %adjust ymax

          end

Thanks
