This loop plots 1 plot with 3 subplots on the same Figure ii times. I cannot figure out how though to label each of the 4 plot with a unique name as the loop progresses. I can use the title, but it only names one of the plots which leaves the other 3 in question to which they are.

for iv = mod((1:numel(k)),12)
    k_i = k(iv);
    figure (k_i)
    DataAnalPlot([c(1:ii,k_i) p(1:ii,k_i)],[c(1:ii,k_i+1) p(1:ii,k_i+1)],[c(1:ii,k_i+2) p(1:ii,k_i+2)],[c(1:ii,k_i+3) p(1:ii,k_i+3)]);
end

First of all, don't use figure() in the loop - use subplot() instead. In the loop you can use sprintf() to build a caption, and then use title() to display it over the plot.

Assuming iv takes on the values 1, 2, 3, and 4:

subplot(2, 2, iv);
caption = sprintf('This is plot #%d', iv);
title(caption, 'FontSize', 20);

For any future visitors I figured out that you can do it this way: Create a cell with the title you want each plot to take, for example months, Note that the number of entries in your cell should match the number of subplots, 1 title for each plot

cellmonth={'January','February','March','April','May','June','July'...

,'August','September','October','November','December'};

then you write a for loop with the number of subplots you want

for i=1:12

title(cellmonth(1,j))

.

end

Hi, thanks for the answer. could you please let me know how I can move each title to up on the left?

Try this:

for k = 1 : 12
	subplot(4, 3, k);
	caption = sprintf('Month #%d', k); % Caption changes depending on k
	title(caption, 'FontSize', 20, 'HorizontalAlignment', 'right');
end
