draw a histogram from an array

I now have an array

date    visitors
------ --------
1/1     5
1/2     10
1/3     12

What is the simplest way to draw a histogram of visitors?

Did you try

bar(t.Data, t.Visitors);
grid on;
xlabel('Date');
ylabel('Number of Visitors');

This assumes that your histogram is in a table like you showed.

histogram(t.Visitors)

You'd need more than 3 samples. But if you have like hundreds of days, then that could get you a distribution of how many people visited during a certain interval of time (like one day or one week).
