I would like to obtain a vector that summarize a certain quantity over all the months.
I want to obtain the name of each month on te x-axis elements but it's not possible whit my script.
I can obtain the graph but then i'm not able to edit the x-element's name.
M=[1 2 3 4 5 6 7 8 9 10 11 12];
Q=[4 8 6 5 3 15 26 17 40 21 19 10];
plot(M,Q)
I try this but it dosent work.
Months={"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};
Q=[4 8 6 5 3 15 26 17 40 21 19 10 30];

Your M and Q should be of same size. In your case M is 1X12 and Q is 1X13, thats is why you are getting error.

Here you go, you can overwrite the ticks with a string:
% data
M = [1 2 3 4 5 6 7 8 9 10 11 12];
Months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];
Q = [4 8 6 5 3 15 26 17 40 21 19 10];
% Plot the figure
figure
plot(M,Q)
% Define the tick locations, and label them
set(gca,'XTick',M)
set(gca,'XTickLabel',Months)
ylabel('Y data')
xlabel('Month of the year')
