Hello,
I've plotted a histogram of some data. Here it is http://dl.dropbox.com/u/54057365/All/departure%20time.JPG
How would I plot a cumulative distribution curve over the histogram? Also why is there gaps between the bars?
I'm trying to a achieve a graph like this

Many thanks
DepartureTimes = load('Departure Times (hr).txt')
h = hist(DepartureTimes,24);
h = h/sum(h);
bar(h, 'DisplayName', 'Depature Times');
legend('show');
xlim([5 25])
