The evangelical Christian movement is taking over
the entire country! I hadn't realized they had moved
into software. :-(

I think you are probably going to have to roll your own
here, but I should think it should be easy if you just
call Label_Date from within your own routine.

Hi,
you can write your own labelling function which calculates a string
(i.e. the label) from input data such as axis (x, y or z), index of
tickmark and x value. You then set
xtickformat='my_func'
See documentation here: http://idlastro.gsfc.nasa.gov/idl_html_help/Graphics_Keyword s.html#wp332347
or IDL documentation for (X|Y|Z)TICKFORMAT
Cheers
