I have 1x720 data. I determined my threshold value as 3 for these data. I want to draw a histogram. I want to write as wheeze if the values in this histogram are less than 3, and non wheeze if they are greater than 3. I want it to look like the sample histogram below. How can I do this? Thank you.

Do you want to make it easy for people to help you by attaching your actual data? Or should they just use something like

data = 6 * rand(1, 720);

load data; % loads data into vector mci
threshold = 3;
upper = ceil(max(mci));
d = histcounts(mci, 0:upper);
bar(1:threshold, d(1:threshold), 'facecolor', 'k');
axis([0 upper 0 max(d)*1.05]);
hold on;
bar(threshold+1:upper, d(threshold+1:upper), 'facecolor', 'w');
set(gca,'ticklength', [0 0]);
set(gca,'xtick', 0.5 + 0:upper);
set(gca,'xticklabels', 0:upper);
legend({'wheeze' 'non-wheeze'});
