Well, except for the fact that this gets the letters in
exactly the opposite order of the desired result, I guess
this is "something like" what you need. :-)

I would do it like this. But I note that U...A is not 12
letters, but 11. You need this from W...A if you are going
to do it correctly.

First, create this tick formatting function.

FUNCTION ValToStr, axis, index, value

letters = Reverse(Bindgen(26))
thisLetter = String(letters[2*index] + 62B)

RETURN, thisLetter
END

Then, apply it like this:

IDL> plot,indgen(12),XTICKS=11,XTICKFORMAT='valtostr'

Cheers,

David
