Here are some routines to do Gregorian
labeling of stacked time series plots. 
The main routine is called TIMEPLT.M.
Try out the routine TIMETEST.M to see
how this works.

IMPORTANT! If you resize the
window after drawing a vector stick plot, you
must rerun timeplt to get the correct
orientation of the sticks!  This goes for
printing too.  Make sure your printer page 
has the same aspect ratio as your window,
or the sticks will have the wrong orientation!
