Hello to everybody, I'm not a real expert on Matlab use, but I need to be more confident with it because I have to write my master thesis by using this software. I have a problem with a figure: I have plot an historical data series that have a monthly frequency data, I would like that in axes x do not appear the number that Matlab gives to my dates, but the dates themselves (01-2000, or Jan-00, or something like this instead of 10, 20, ... ). I hope to have well explained my problem. Thank you!! Michela

You could use the datetick command, which has many date format options for you to choose from. Read the documentation carefully and pick the best one for your needs. Here is an example of how it can be used:
>> t = (1900:10:1990).';
>> p = [75,91,105,123,131,150,179,203,226,249].';
>> bar(datenum(t,1,1),p)
>> datetick('x',28)
Which creates this:

Note that the X-axis needs to be supplied with a serial date number, not just a values that is the year that you want. Have a look at my example and you can see that I use the function datenum to convert a vector of years (1900,1910,...) into serial date numbers, and these are the X-values that I plotted.
