Occasion: This week I shall be finishing 1 1/2 years of PhD. My rate of going for a hair cut has reduced so much that I fear that by the end of my PhD I might not need a hair-cut.
Matlab Code (sans Annotation):
plot(x, exp(-x)+0.05*sin(y), 'linewidth', 3);
set(gca, 'xlim', [0,3]);
set(gca, 'FontSize', 20);
ylabel('Need for Haircut', 'FontSize', 30);
xlabel('Time spent as PhD student (years)', 'FontSize', 30);
