Plotting against dates - datetick

I am plotting prices against dates using plot(date,price). date array is stored in the datenum form.

in order to read the dates along x-axis I use :

datetick('x','dd-mm-yy'); xlim([date(1,1) date(length(date),1)]); grid on;

there are two issues here: 1) i cannot tweak the interval on the date axis i.e. want to have labels every 3mths, 6 month or 2 weeks (as pref.)

2) i am not sure if i am handling dates and dateaxis in the best way. please suggest any alternatives.

Check out this MATLAB Central submission:

If it doesn't help you directly, you can learn a lot from editing and working through the code.

It can be a bit painful, but one solution is to adjust the tick spacing before you call datetick(), and then use the 'keepticks' option of datetick().
