MATLAB: How do i set pairs(like (5,6)) instead of single values(like 5) on x-axis

Question

I have a plot and I want to set pairs of values on the x-axis, like (5,6) (5,5) (7,7) etc. instead of single values. Does anyone know how is this possible?

Answer 1

>> plot(rand(3))
>> set(gca,'XTick',1:3,'XTickLabel',{'(1,2)','(3,4)','(5,6)'})
