MATLAB: Histogram using Date Stamps

datestampdurationhistogram

I have three years of dates and I want to know how to make a histogram only taking months into consideration.

The data is in datestam format, so when I plot a histogram is separates the months for each year.

How do I do this?

Thanks!

Oh, if it's the histogram of the dates you want, then groupsummary may not be the best tool (sorry Adam!)

histogram(yourdatetimevector.Month, 'BinMethod', 'integers')

You could request output from histogram():

h = histogram(S,'Normalization','probability');

and access properties such as h.BinEdges, h.BinCounts, h.Values, etc, described here.

Or you could use histcounts(), described here, after you plot your histogram:

histogram(S,'Normalization','probability');
[binCounts,binEdges] = histcounts(S,'Normalization','probability');

histogram(YourImage(:), 16)
