Hey everyone,

I am trying to plot a time series that consists of 8760 data points with a value for each hour of the year. I want to show the values in the plot and display the months of the year on the x axis. I found the function dateaxis which seemed pretty easy, but matlab only displays four months of the year... I want all twelve...

Is there a way to tell dateaxis how many months to plot? If there is not, can you tell me a different way on how to plot my time series??

Thanks a lot!

This works to plot months:

x = 0:8759;
y = sin(2*pi*x/(24*30.5));          % Something To Plot
xd = datenum([2014 01 01]) + x/24;
figure(1)
plot(xd, y)
set(gca, 'XTick', 0:11)
datetick('x', 'mmm')
axis tight
