How to manipulate xtick labels?

Hi!

I am plotting a simple data set, say -

plot(1:21,1:21);

Now, obviously the x axis will show 1 to 21. But I want to change it to year 1984 to 2021 (with proper space gap in the x axis). How can I do it?

What you mean by changing into year 1984 to 2021 from 1:21? Show an example.

I am using this code to plot x axis ticks

Year_List = {'1984'; '1986';'1988';'1990';'1992';'1994';'1996';'1998';...
    '2000';'2002';'2004';'2006';'2008';'2010';'2012';'2014';'2016';'2018';'2020'};
Gaps = [1:1:19];
xticks(Gaps);
xticklabels(Year_List);

What else do you need in addition to the following?

plot(1:21,1:21);

Year_List = {'1984'; '1986';'1988';'1990';'1992';'1994';'1996';'1998';...
    '2000';'2002';'2004';'2006';'2008';'2010';'2012';'2014';'2016';'2018';'2020'};
Gaps = [1:1:19];

xticks(Gaps);
xticklabels(Year_List);
set(gca, 'FontSize', 8);
grid on
