MATLAB: Plotting only the year of a column vector with full date

dataMATLABvector

I have a column vector with the dates in the format "MM/dd/yyyy." I would like to plot this against another vector, but only using the year part of the date. How can I extract the yyyy part and assign it to a new vector variable to be able to plot it?

Best Answer

Use xtickformat or datetick
Demo:
 dt = datetime(1999,01,01) + days(1:100:5000); 
 y = rand(size(dt)); 
 ax = gca(); 
 plot(dt,y)
 xtickformat(ax, 'yyyy') 
●
 % or
 datetick(ax, 'x', 'yyyy', 'keeplimits')
