y=[1 2 3 4 5 6]
x=['a','b','c','d','e','f']
plot(x,y)

Note that in MATLAB [] is a concatenation operator and not a list operator, so this code:
x=['a','b','c','d','e','f']
is equivalent to this:
x = 'abcdef'
You can use a cell array or the string class to store strings as separate elements of an array.

y=[1 2 3 4 5 6]
x=['a','b','c','d','e','f']
plot(y)
set(gca,'xticklabel',x.')

Hello! and if I want to select just a part of the x table, how can I do? For example, I would like to plot x values 'b' to 'e'. Thank you!
