plotting all the years of a time period vertically to the x-axis

Dear all,

I have ns=2838 daily observations y. I plot these data using the following commands

 startDate = datenum('07-01-1996');
endDate = datenum('07-30-2007');
xData = linspace(startDate,endDate,ns);

 figure
plot(xData, y )
datetick( 'x','yyyy','keepticks' )

In this case, I obtain the following sequence of years on the x-axis:

 1995, 19997, 1998,2000,2001,2002,2004, 2005, 2006, 2008

But I would like to have, vertically to the x-axis, all the years starting from 01/1996 till 30/2007, that is

 01/1996, 01/1997, 01/1998 , 01/1999 01/2000 , 01/2001, 01/2002 ...

How could I modify the above code to do that?

Thanks in advance

ns=2838;
startDate = datenum('07-01-1996');
endDate = datenum('07-30-2007');
xData = linspace(startDate,endDate,ns);
plot(xData, randn(ns))
xt=arrayfun(@num2str,(1996:2007),'un',0)
xl=get(gca,'xlim')
set(gca,'xtick',linspace(xl(1) ,xl(2),numel(xt)),'xticklabel',xt)

thanks Azzi. it works fine. the only remaining problem is that the plot ends before july 2007. how is that possible

Thanks for your patience!

close
ns=2838;
startDate = datenum('07-01-1996');
endDate = datenum('07-30-2007');
xData = linspace(startDate,endDate,ns);
plot(xData, randn(ns))
xt=arrayfun(@num2str,(1996:2007),'un',0)
xl=[startDate endDate]
set(gca,'xlim',xl)
set(gca,'xtick',linspace(xl(1) ,xl(2),numel(xt)),'xticklabel',xt)

Look at this http://www.mathworks.com/support/solutions/en/data/1-15TK6/

thanks Azzi, I was also wondering how the code changes if I want to plot (not vertically) all the years, that is

 1996, 19997, 1998, 1999, 2000,2001,2002 ...

[Azzi Abdelmalek]

Give a short example with data

[antonet]

For instance,

 ns=2838;

 startDate = datenum('07-01-1996');
endDate = datenum('07-30-2007');
xData = linspace(startDate,endDate,ns);

 figure
subplot(2, 1, 1);
    plot(xData, randn(ns))
  datetick('x','yyyy','keepticks')

Two comments:

A) I do not obtain all the years on the x-axis. the year 1999, for instance, is missing. I want to have all the years from 1996 to july 2007 on the x axis.

B) As you can see, the matlab graph does not start from 1996 but from 1995. Similarly, the graph ends in 2008 which is a redundant year since the time period ends in july 2007. So can "throw" these redundant years?

Many thanks
