graphic axis tic label with two lines

[Jens Wunderlich]

  Hi all,

is it possible to have the tics of let's say the x-axis labelled with a 
two-lines string?
In my case I like to have labels with date and time. These labels are 
too long and are printed overlapping. To avoid this it would be nice to 
have the time below the date.

I tried:

//working example with all in one line
ha=gca();

ha.x_ticks.labels(1) = '2010-09-01 20:55';

//this doesn't work
ha.x_ticks.labels(2) = ['2010-09-01' '20:55' ]

Any help would be appreciated.

Thanks,
Jens
