Three plots in one bar graph: Need different ticklabels

I'm doing a bar graph, in which I want three bars each with a different color. To do this, I have used the hold command and three plots (Bonus question: Is there an easier way to do this?)

Anyway, I need the ticklabel to be specific time values, but I can't seem to make that work.

subplot(2,3,6)
hold on
bar(1,subject.correct(1,1), 'r')
bar(2,subject.correct(2,1), 'b')
bar(3,subject.correct(3,1), 'y')
hold off
title('Reaktionshastighed - Korrekte svar')
xlabel('Testnummer')
ylabel('Korrekte svar (%)')
set(gca,'XTickLabel',{time_1, time_2, time_3})

Previously, my code can be seen below, which worked perfectly with my Xticklabel, however all three bars were the same color:

bar(1:3,subject.correct, 'r')

No answers in 11 hours to what may seem like a pretty straight-forward question. Is it possible at all with the current Matlab build?
