Modify axis tick frequency

Dear Matlab community,

I have successfully produced the following plot:

by using the following code:

dn=datenum(1926,7+[0:(2014-1926)*12+5].',1);
datestr([dn(1),dn(end)]);
plot(dn,y);
xlim([dn(1) dn(end)]);
datetick('x','mm/yyyy','keeplimits');

I now would like to adjust the frequency of the x-axis date ticks, but I cannot make sense of the function. I believe datetick is set on auto mode, where it produces a default number of ticks. I am looking for 1-year and 5-year intervals.

Thank you very much! The help from the MATLAB community has helped me a great deal!

Chris

If you want 1 year and 5 year ticks both at the same time then you would be wanting the 1 year ticks to be Minor Ticks and the 5 year ticks to be the major ticks. See http://www.mathworks.com/matlabcentral/answers/97759-how-do-i-add-minor-ticks-to-a-graph for information about setting minor ticks.

For the 5 year ticks:

tick5 = datenum(1930:5:2014,1,1);
set(gca, 'xtick', tick5);
datetick('x', 'yyyy', 'keepticks');

Thank you very much!

tick5 = datetime(1930:2014,1,1);

set(gca, 'Xtick', tick5)

instead of datenum, you can use datetime.
