I have a data set with two columns, in the second there are daily historical data which I would like to plot. This is no problem. In the first column of the data set, there is the respective data which should be displayed on the x-axis.
The thing is that the whole data set consists of more than 5000 rows and I do not want to have displayed 5000 dates on the x-axis but just the years, as follows
2000 2001 2002 2003 2004 2005 2006 2007 2008 2009
In excel that is no big deal but I do not know how to do that in Matlab
No products are associated with this question.
Look at this example
dates=datenum('01/01/2000'):datenum('01/01/2009') y=sin(0.01*dates) plot(dates,y) d=datevec(dates) [a,idx]=unique(d(:,1),'first') set(gca,'xtick',dates(idx),'xticklabel',a)
Sounds like you need to adjust the "ticks" of your x-axis.
