See my recommendation to use datetime data when plotting, related to your other question, here:

If you use datetime data, you can easily query the datetime format from the axes using the following functions

For example,

>> plot(datetime('today'):caldays:30*caldays+datetime('today'),1:31)
>> xfmt = xtickformat

xfmt =

    'MMM dd'
