Set labels as you want

Let's plot something first.



t=-pi:pi/100:pi;
x=sin(t);
plot(t,x)


And here is what the plot looks like:

Then I want to set the range of x labels from -4 to 12.

xlim([-4 12])

Then I want to show the positive labels only.

set(gca,'xtick',0:1:12)

Then I want to show something different.
set(gca,'xticklabel',{'Jan', 'Feb','Mar', 'and','what', 'ever','you', 'want', 'it', 'to', 'be','!','!@#$@#$'})

Done!
