How to change the x ticket lables in a plot?

Hi, I have : x=1:12 %the index of months

y=x.^2;

plot(x,y)

No I want to change the position of x labels from below the tickets to the middle of interval (between every 2 tickets). Can you please help me?

It is not clear what you intend. Where exactly do you want the ticklabels? At [1 3 5 7 9 11] or what?

   x=1:12 %the index of months
   y=x.^2;
   plot(x,y)
   set(gca,'xtick',[ 1 3 5 7 9 11])  % use whatever you want

Try

x = 1:12;
y = x.^2;
plot(x,y); 
tickLocations = [3,6,9]; % change to whatever you want
tickLabels    = {'3','6','9'}; % change to whatever you want
set(gca,'xTick',tickLocations,'xTickLabel',tickLabels)
