You've made an announcement, not a question. Do you have a question? Well, I have one. Do you have another array that says what day each row is. Like okay, row 55 has the measurement made on day #55, but is that March 13, July 4, November 24, or what???? How can we group by months if we don't know which row is in which month?

dv = datevec(SerialDateNumbers);
month_num = dv(:,2);
MonthLab = {'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'};
boxplot(data, month_num, 'Labels', MonthLab);

Hi, I have a similar need, the only difference is that i need a continuous time-series boxplot by month, i.e., not joining data of same months of different years, all in the same month boxplot.. The result will be like: jan/2019, feb/2019...... jan/2020, fev/2020... and so on.
