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.

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).
