You can use sprintf to format the title within the loop, for instance you could store all your title in a cell array for future reference, but in a loop that would look like this:
TitleArray = cell(1,50);
for i = 1:50
A{i} = sprintf('Test A at %i mins\n',i);
end
Of course you could just put the title after you draw the plot:
hold all
for i =1:50
...you code for generating the plots
title(sprintf('Test A at %i mins\n',i));
end
hold off
Do you want to generate 50 plots in the same figure or all on one big figure?
