Hi, I attached time(datetime, 1980.1.1~2015.12.31) and set y value as P=[1:432].
* I convert date form.I also attached original time form(original_time)
time = datetime(original_form,'ConvertFrom','datenum');
If i draw the plot, i got below figure.
plot(time,P);
datetick('x','yy/mm','keeplimits');
grid on
And i want to add constant vertical line on every March.
I couldn't fine proper method. Please help me :(

Following @Walter Roberson answer, you could change the xticks for the plot axis and then draw xline as usual for every march month
